Besides running it locally, you can select to run your application on a remote machine via SSH or in a Docker container. For more information, refer to [Run targets](https:\/\/www.jetbrains.com\/help\/idea\/run-targets.html). |\n| Store as project file | Save the run configuration settings to a file that you can share with other team members. The default location is .idea\/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.By default, this option is disabled, and IntelliJ IDEA stores run configuration settings in .idea\/workspace.xml. |\n\n## Required options\n| Item | Description |\n|---|---|\n| JRE | Specify the runtime environment that IntelliJ IDEA should use to run the application. By default, IntelliJ IDEA uses the latest available JDK from the module dependencies. |\n| Main class | Specify the fully qualified name of the class to be executed. |\n| Program arguments | Specify a list of arguments to be passed to the application in the format you would use on the command line. Use the same rules as for specifying VM options. |\n| Working directory | Specify the working directory to be used for running the application. This directory is the starting point for all relative input and output paths. By default, the working directory is the project root. |\n\n## More options\nYou can also configure additional properties for the Application run\/debug configuration type. To access them, click Modify options:\n\n![Run\/Debug Configuration: Application, More Options](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/run-debug-application-more.png)\n\n## Operating system\n| Item | Description |\n|---|---|\n| Allow multiple instances | Allow multiple instances of this run configuration to execute at the same time. By default, this option is disabled, which means that when you run the configuration, other active sessions of the configuration will terminate. |\n| Environment variables | Click ![the Browse button](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.general.inlineVariables.svg) to open the Environment Variables dialog where you can create variables and specify their values. |\n| Redirect input | Enables redirecting data from a text file to standard input. Use this option if your program requires some input, and you want to read the values from a file instead of typing them in the Run console. To enable redirecting, select the checkbox and specify the path to the target text file. |\n\n## Java\nThe following options are specific to the Java compiler and runtime:\n\n| Item | Description |\n|---|---|\n| Do not build before run | Run the application straight away without launching the build process. |\n| Use classpath of module | Select the module whose classpath should be used to run the application. |\n| Modify classpath | If necessary, specify another classpath or select dependencies that you want to exclude from the classpath. This option is necessary in cases when the runtime classpath is different from the compile classpath (debug libraries, different locations, and so on).Use the ![Up](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.expui.general.moveUp.svg) and ![Down](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.expui.general.moveDown.svg) buttons to sort dependencies on the list. The order of dependencies is important as IntelliJ IDEA will process them in the same order as they are specified in the list. |\n| Add dependencies with “provided” scope to classpath | Add the dependencies with the provided scope to the runtime classpath. |\n| Shorten command line | Select a method that will be used to shorten the command line if the classpath gets too long, or you have many VM arguments that exceed your OS command line length limitation. The choice of option depends on the class loader implementation. Note that some frameworks do not support JAR manifest, while other frameworks with custom class loaders will not work well with the classpath.file option.none: IntelliJ IDEA will not shorten a long classpath. If the command line exceeds the OS limitation, IntelliJ IDEA will be unable to run your application and will display a message suggesting that you specify the shortening method. JAR manifest: IntelliJ IDEA will pass a long classpath via a temporary classpath.jar. The original classpath is defined in the manifest file as a `class-path` attribute in classpath.jar. Note that you will be able to preview the full command line if it was shortened using this method, not just the classpath of the temporary classpath.jar. classpath.file: IntelliJ IDEA will write a long classpath into a text file. @argFiles (Java 9+): the command-line length limitations will be overcome using the [@argument files option](https:\/\/docs.oracle.com\/javase\/9\/tools\/java.htm#JSWOR-GUID-4856361B-8BFD-4964-AE84-121F5F6CF111).note This setting is shared if you select to share your run\/debug configuration, so the same method will be applied for your team members irrespective of their operating system. |\n| VM options | Specify the options to be passed to the Java virtual machine when launching the application, for example, `-mx`, `-verbose`, and so on.When specifying JVM options, follow these rules:Use spaces to separate individual options. If the value of an option includes spaces, enclose either the value or the actual spaces with double quotes. If an option includes double quotes as part of the value, escape the double quotes using backslashes. You can pass environment variable values to custom Java properties.Use code completion in this field: start typing the name of a flag, and the IDE suggests a list of available command line options. This works for `-XX:` and `-X` options and some standard options that are not configured by IntelliJ IDEA automatically, like `-ea`, but not for `-cp` or `–release`.The `-classpath` option specified in this field overrides the classpath of the module. |\n\n## Logs\nThe following options are related to logging the execution of this configuration.

By default, IntelliJ IDEA uses the latest available JDK from the module dependencies. |\n| Main class | Specify the fully qualified name of the class to be executed. |\n| Program arguments | Specify a list of arguments to be passed to the application in the format you would use on the command line. Use the same rules as for specifying VM options. |\n| Working directory | Specify the working directory to be used for running the application. This directory is the starting point for all relative input and output paths. By default, the working directory is the project root. |\n\nMore options\n\nYou can also configure additional properties for the Application run\/debug configuration type. To access them, click Modify options:\n\n![Run\/Debug Configuration: Application, More Options](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/run-debug-application-more.png)\n\nOperating system\n\n| Item | Description |\n|---|---|\n| Allow multiple instances | Allow multiple instances of this run configuration to execute at the same time. By default, this option is disabled, which means that when you run the configuration, other active sessions of the configuration will terminate. |\n| Environment variables | Click ![the Browse button](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.general.inlineVariables.svg) to open the Environment Variables dialog where you can create variables and specify their values. |\n| Redirect input | Enables redirecting data from a text file to standard input. Use this option if your program requires some input, and you want to read the values from a file instead of typing them in the Run console. To enable redirecting, select the checkbox and specify the path to the target text file. |\n\nJava\n\nThe following options are specific to the Java compiler and runtime:\n\n| Item | Description |\n|---|---|\n| Do not build before run | Run the application straight away without launching the build process. |\n| Use classpath of module | Select the module whose classpath should be used to run the application. |\n| Modify classpath | If necessary, specify another classpath or select dependencies that you want to exclude from the classpath. This option is necessary in cases when the runtime classpath is different from the compile classpath (debug libraries, different locations, and so on).Use the ![Up](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.expui.general.moveUp.svg) and ![Down](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.expui.general.moveDown.svg) buttons to sort dependencies on the list. The order of dependencies is important as IntelliJ IDEA will process them in the same order as they are specified in the list. |\n| Add dependencies with “provided” scope to classpath | Add the dependencies with the provided scope to the runtime classpath. |\n| Shorten command line | Select a method that will be used to shorten the command line if the classpath gets too long, or you have many VM arguments that exceed your OS command line length limitation. The choice of option depends on the class loader implementation. Note that some frameworks do not support JAR manifest, while other frameworks with custom class loaders will not work well with the classpath.file option.none: IntelliJ IDEA will not shorten a long classpath. If the command line exceeds the OS limitation, IntelliJ IDEA will be unable to run your application and will display a message suggesting that you specify the shortening method. JAR manifest: IntelliJ IDEA will pass a long classpath via a temporary classpath.jar. The original classpath is defined in the manifest file as a `class-path` attribute in classpath.jar. Note that you will be able to preview the full command line if it was shortened using this method, not just the classpath of the temporary classpath.jar. classpath.file: IntelliJ IDEA will write a long classpath into a text file. @argFiles (Java 9+): the command-line length limitations will be overcome using the [@argument files option](https:\/\/docs.oracle.com\/javase\/9\/tools\/java.htm#JSWOR-GUID-4856361B-8BFD-4964-AE84-121F5F6CF111).note This setting is shared if you select to share your run\/debug configuration, so the same method will be applied for your team members irrespective of their operating system. |\n| VM options | Specify the options to be passed to the Java virtual machine when launching the application, for example, `-mx`, `-verbose`, and so on.When specifying JVM options, follow these rules:Use spaces to separate individual options. If the value of an option includes spaces, enclose either the value or the actual spaces with double quotes. If an option includes double quotes as part of the value, escape the double quotes using backslashes. You can pass environment variable values to custom Java properties.Use code completion in this field: start typing the name of a flag, and the IDE suggests a list of available command line options. This works for `-XX:` and `-X` options and some standard options that are not configured by IntelliJ IDEA automatically, like `-ea`, but not for `-cp` or `–release`.The `-classpath` option specified in this field overrides the classpath of the module. |\n\nLogs\n\nThe following options are related to logging the execution of this configuration. For more information, refer to [Logs](https:\/\/www.jetbrains.com\/help\/idea\/setting-log-options.html).\n\n| Item | Description |\n|---|---|\n| Specify logs to be shown in the console | Specify which log files to display while running the application.Click ![the Add button](https:\/\/resources.jetbrains.com\/help\/img\/idea\/2026.1\/app.expui.general.add.svg) to add a new log.

Log File Location: Specify the path to the log file or an [Ant pattern](https:\/\/ant.apache.org\/manual\/dirtasks.html). If several files of a rolling log match the pattern, IntelliJ IDEA will display the most recent one. Show all files coverable by pattern: Show all logs that match the pattern.For logs in the table, you can configure the following options:Is Active: Display the specified log file. Skip Content: Do not display old log messages from previous runs. |\n| Save console output to file | Save the console output to the specified location.

This configuration compiles and runs your Java program – similar to when you use the `javac` and `java` commands. . ### Open the run configuration 1. In the main menu, go to Run \\| Edit Configurations. 2. In the Run/Debug Configuration dialog: - To create a new configuration, click ![Add](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.add.svg) on the toolbar or press `Alt``Insert` and select Application. - Alternatively, click an existing Application configuration in the list on the left. On the right, you will see configuration options. ![Run/Debug Configuration: Application](https://resources.jetbrains.com/help/img/idea/2026.1/run-java-app-main-config.png) > ### tip > You can use `Ctrl``Space` to let IntelliJ IDEA [help you fill in the fields](https://www.jetbrains.com/help/idea/auto-completing-code.html) in this dialog. \| \| \| \|---\|---\| \| Name \| Specify a name for the run configuration to quickly identify it among others when editing or running. \| \| Run on \| Select the target environment where you want to run the configuration. Besides running it locally, you can select to run your application on a remote machine via SSH or in a Docker container. For more information, refer to [Run targets](https://www.jetbrains.com/help/idea/run-targets.html). \| \| Store as project file \| Save the run configuration settings to a file that you can share with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.By default, this option is disabled, and IntelliJ IDEA stores run configuration settings in .idea/workspace.xml. \| ## Required options \| Item \| Description \| \|---\|---\| \| JRE \| Specify the runtime environment that IntelliJ IDEA should use to run the application. By default, IntelliJ IDEA uses the latest available JDK from the module dependencies. \| \| Main class \| Specify the fully qualified name of the class to be executed. \| \| Program arguments \| Specify a list of arguments to be passed to the application in the format you would use on the command line. Use the same rules as for specifying VM options. \| \| Working directory \| Specify the working directory to be used for running the application. This directory is the starting point for all relative input and output paths. By default, the working directory is the project root. \| ## More options You can also configure additional properties for the Application run/debug configuration type. To access them, click Modify options: ![Run/Debug Configuration: Application, More Options](https://resources.jetbrains.com/help/img/idea/2026.1/run-debug-application-more.png) ## Operating system \| Item \| Description \| \|---\|---\| \| Allow multiple instances \| Allow multiple instances of this run configuration to execute at the same time. By default, this option is disabled, which means that when you run the configuration, other active sessions of the configuration will terminate. \| \| Environment variables \| Click ![the Browse button](https://resources.jetbrains.com/help/img/idea/2026.1/app.general.inlineVariables.svg) to open the Environment Variables dialog where you can create variables and specify their values. \| \| Redirect input \| Enables redirecting data from a text file to standard input. Use this option if your program requires some input, and you want to read the values from a file instead of typing them in the Run console. To enable redirecting, select the checkbox and specify the path to the target text file. \| ## Java The following options are specific to the Java compiler and runtime: \| Item \| Description \| \|---\|---\| \| Do not build before run \| Run the application straight away without launching the build process. \| \| Use classpath of module \| Select the module whose classpath should be used to run the application. \| \| Modify classpath \| If necessary, specify another classpath or select dependencies that you want to exclude from the classpath. This option is necessary in cases when the runtime classpath is different from the compile classpath (debug libraries, different locations, and so on).Use the ![Up](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.moveUp.svg) and ![Down](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.moveDown.svg) buttons to sort dependencies on the list. The order of dependencies is important as IntelliJ IDEA will process them in the same order as they are specified in the list. \| \| Add dependencies with “provided” scope to classpath \| Add the dependencies with the provided scope to the runtime classpath. \| \| Shorten command line \| Select a method that will be used to shorten the command line if the classpath gets too long, or you have many VM arguments that exceed your OS command line length limitation. The choice of option depends on the class loader implementation. Note that some frameworks do not support JAR manifest, while other frameworks with custom class loaders will not work well with the classpath.file option.none: IntelliJ IDEA will not shorten a long classpath. If the command line exceeds the OS limitation, IntelliJ IDEA will be unable to run your application and will display a message suggesting that you specify the shortening method. JAR manifest: IntelliJ IDEA will pass a long classpath via a temporary classpath.jar. The original classpath is defined in the manifest file as a `class-path` attribute in classpath.jar. Note that you will be able to preview the full command line if it was shortened using this method, not just the classpath of the temporary classpath.jar. classpath.file: IntelliJ IDEA will write a long classpath into a text file. @argFiles (Java 9+): the command-line length limitations will be overcome using the [@argument files option](https://docs.oracle.com/javase/9/tools/java.htm#JSWOR-GUID-4856361B-8BFD-4964-AE84-121F5F6CF111).note This setting is shared if you select to share your run/debug configuration, so the same method will be applied for your team members irrespective of their operating system. \| \| VM options \| Specify the options to be passed to the Java virtual machine when launching the application, for example, `-mx`, `-verbose`, and so on.When specifying JVM options, follow these rules:Use spaces to separate individual options. If the value of an option includes spaces, enclose either the value or the actual spaces with double quotes. If an option includes double quotes as part of the value, escape the double quotes using backslashes. You can pass environment variable values to custom Java properties.Use code completion in this field: start typing the name of a flag, and the IDE suggests a list of available command line options. This works for `-XX:` and `-X` options and some standard options that are not configured by IntelliJ IDEA automatically, like `-ea`, but not for `-cp` or `–release`.The `-classpath` option specified in this field overrides the classpath of the module. \| ## Logs The following options are related to logging the execution of this configuration. For more information, refer to [Logs](https://www.jetbrains.com/help/idea/setting-log-options.html). \| Item \| Description \| \|---\|---\| \| Specify logs to be shown in the console \| Specify which log files to display while running the application.Click ![the Add button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.add.svg) to add a new log. In the Edit Log Files Aliases dialog, configure the following:Alias: The name of the tab where the log will be displayed. Log File Location: Specify the path to the log file or an [Ant pattern](https://ant.apache.org/manual/dirtasks.html). If several files of a rolling log match the pattern, IntelliJ IDEA will display the most recent one. Show all files coverable by pattern: Show all logs that match the pattern.For logs in the table, you can configure the following options:Is Active: Display the specified log file. Skip Content: Do not display old log messages from previous runs. \| \| Save console output to file \| Save the console output to the specified location. Type the path manually or click the browse button and point to the desired location in the dialog that opens. \| \| Show console when a message is printed to stdout \| Activate the console when the application writes to the standard output stream. \| \| Show console when a message is printed to stderr \| Activate the console when the application writes to the standard error stream. \| ## Code Coverage The following options are related to code coverage. For more information, refer to [Code coverage](https://www.jetbrains.com/help/idea/code-coverage.html). \| Item \| Description \| \|---\|---\| \| Specify classes and packages \| In this table, specify classes and packages to be measured. Click ![the Add button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.add.svg) and select ![the Add Class button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.nodes.class.svg) Add Class or ![the Add Package button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.nodes.package.png) Add Package to specify. You can also remove classes and packages from the list by selecting them in the list and clicking the ![remove the package](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.remove.svg) button. \| \| Exclude classes and packages \| Specify classes and packages that you want to exclude from coverage.Click ![the Add button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.general.add.svg) and select ![the Add Class button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.nodes.class.svg) Add Class or ![the Add Package button](https://resources.jetbrains.com/help/img/idea/2026.1/app.expui.nodes.package.png) Add Package to specify classes and packages. \| ## Before Launch In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list. \| Item \| Description \| \|---\|---\| \| Add before launch task \| Enable this option to add one of the following available tasks:Launch Web Browser: select this option to have a browser started. In the dialog that opens, select the type of the browser and provide the start URL. Also, specify if you want the browser be launched with JavaScript debugger. Run External tool: run an external application. In the dialog that opens, select one or multiple applications you want to run. If it is not defined in IntelliJ IDEA yet, add its definition. For more information, refer to [External tools](https://www.jetbrains.com/help/idea/configuring-third-party-tools.html). Run Another Configuration: select to execute another run/debug configuration and wait until it finishes before starting the current configuration. If you want to run several configurations in parallel, use a [compound run/debug configuration](https://www.jetbrains.com/help/idea/run-debug-multiple.html#compound-configs). Run Remote External Tool: add a [remote SSH external tool](https://www.jetbrains.com/help/idea/settings-tools-remote-ssh-external-tools.html). Run Gradle task: run a [Gradle task](https://www.jetbrains.com/help/idea/create-run-debug-configuration-gradle-tasks.html). In the dialog that opens, specify the task and provide additional configuration if necessary. Build: select to compile the specified module. The [Build Module](https://www.jetbrains.com/help/idea/compiling-applications.html#compile_module) action will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration. Build Project: select to compile the entire project. The [Build Project](https://www.jetbrains.com/help/idea/compiling-applications.html#compile_module) action will be executed. If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration. Build, no error check: the same as the Build option, but IntelliJ IDEA will try to start the run/debug configuration irrespective of the compilation results. Build Artifacts: select this option to build an [artifact](https://www.jetbrains.com/help/idea/working-with-artifacts.html) or artifacts. In the dialog that opens, select the artifact or artifacts that should be built.
