Run/Debug Configuration: Gradle

You can run Gradle tasks using run configuration. The default options listed in such configuration are enough to run your task. If you want, you can also create an advanced configuration using additional options or adding more tasks and arguments.

Create a run/debug Gradle configuration

From the main menu, select Add Configuration. Alternatively, right-click any task in the Gradle tool window and select Modify Run Configuration.
Specify a name of your configuration in the Name field to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10 or the Gradle tool window.
If you need, specify Store as project file that saves the file with the run configuration settings, so you can share it 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.
To change the location, select this option and click and in the dialog that opens, add the new location.
If you don't need to specify anything in the Run field, the default tasks such as help and tasks specified in the Before build section. section will be executed. Alternatively, if you are creating a run configuration from the Gradle tool window, the task you have selected will be displayed in this field. However, you can specify additional external tasks and arguments for your run configuration. Use spaces to separate one task from another. If you want to see the available list of Gradle tasks and arguments, click in the field.
Specify the location of your Gradle project.
You can either enter it manually or click and point to the desired location in the dialog that opens. However, if you are creating a run configuration from the Gradle tool window, CLion will display the name of your project automatically.
You can also click Gradle registered projects icon to select an available Gradle module from the list of registered Gradle modules in your existing CLion project.
If you need, you can specify a path to the build script file instead of the project path. This might be helpful if you have a custom build script to which you want to refer.
If you need, specify the environment variables that you want to use in you project.
The following default options are enabled, but you can click Modify options and use the Add Run Options list to add the new options or remove some default ones:
- Open run/debug tool window when started - automatically opens the Run/Debug tool window when the configuration is executed and several debugger options
- Debug Gradle scripts - enables breakpoints in the Gradle scripts.

Add Run Options

The Add Run Options list lets you add more run options to the Run/Debug Configurations dialog or remove some of the default ones from it. The list is divided into various sections, so you can easily navigate through the available options.

Operating System

Item	Description
Allow multiple instances	Select this option to allow running multiple instances of this run configuration in parallel. By default, it is disabled, and when you start this configuration while another instance is still running, CLion suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Java

Item	Description
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. -Xmx1024m -Dspaces="some arg" -Dmy.prop=\"quoted_value\" -Dfoo=${MY_ENV_VAR} 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 CLion 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 .

Item	Description
Specify logs to be shown in the console	Specify which log files to display while running the application. Click 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. If several files of a rolling log match the pattern, CLion 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

Gradle

Item	Description
Debug all tasks on the execution graph	When you select this option, every task in the execution graph will be debugged. For example, all the dependent tasks of the task you are trying to debug.
Debug forked Gradle tasks in separate debug tabs	Select this option to run a debugging process in a separate tab in the Debug tool window.
Run as test	By default, this option is disabled. In such case, CLion doesn't open the Run tool window and doesn't rerun tests tasks if they are up to date. However, if CLion finds test tasks in the run configuration, those are highlighted in the Gradle tool window, CLion doesn't rerun test tasks, but opens the Gradle tool window. The option becomes enabled when you trigger the test execution from the editor using in the gutter or the context menu. In this case, CLion opens the Run tool window and reruns the test tasks each time the execution is triggered even if the tests are up to date. This option might be helpful in controlling the rerunning process of the test tasks in your project.
