IntelliJ IDEA 2021.3 Help

Run/Debug Configuration: Grails

Grails run/debug configuration enables you to run and debug the Grails applications, tests and Web tests.

The dialog consists of the following tabs:

Grails Tab

Item

Description

Module

Select application, for which this run/debug configuration is created. By default, the name of the current module is suggested.

Command line

Type a command to execute a particular target, for example, run-app, or app-engine.

Alternatively, you can execute target as described in the section Run Grails targets.

VM Options

Specify the string to be passed to the VM for launching the application. This string may contain the options such as -mx, -verbose, etc.

When specifying JVM options, follow these rules:

  • Use spaces to separate individual options, for example, -client -ea -Xmx1024m.

  • If an option includes spaces, enclose the spaces or the argument that contains spaces in double quotes, for example, some" "arg or "some arg".

  • If an option includes double quotes (as part of the argument), escape the double quotes using backslashes, for example, -Dmy.prop=\"quoted_value\".

  • You can pass environment variable values to custom Java properties. For example, if you define a variable MY_ENV_VAR, you can pass it to the foo property as follows:

    -Dfoo=${MY_ENV_VAR}

Environment Variables

Click Browse the Browse button to open the Environment Variables dialog box, where you can create variables and specify their values.

Add --classpath

If this checkbox is selected, it means that the user intends to include the dependency directly, by passing --classpath to the command line.

Launch browser

By default, this checkbox is not selected and IntelliJ IDEA uses http://localhost:8080/application_name as default address. Select this checkbox to enter a different address in the field.

Code Coverage tab

Use this tab to configure code coverage monitoring options.

Item

Description

Choose coverage runner

Select the desired code coverage runner.

By default, IntelliJ IDEA uses its own coverage engine with the Sampling mode. You can also choose JaCoCo or Emma for calculating coverage.

Sampling

Select this option to measure code coverage with minimal slow-down.

Tracing

Select this option to collect accurate branch coverage. This mode is available for the IntelliJ IDEA code coverage runner only.

Track per test coverage

Select this checkbox to detect lines covered by one test and all tests covering line. If this checkbox is selected, Track per test coverage becomes available on the toolbar of the coverage statistic popup.

Refer to the section Set coverage in run configurations.

Packages and classes to record code coverage data

Click the Add button and select the Add Class button Add Class or the Add Package button Add Package to specify classes and packages to be measured. You can also remove classes and packages from the list by selecting them in the list and clicking the remove the package button.

Enable coverage in test folders.

If this checkbox is selected, the folders marked as test root_Test.png are included in the code coverage analysis.

Maven Settings Tab

Use this tab to configure Maven settings for running and debugging your application. By default, the Use project settings checkbox is selected and IntelliJ IDEA uses the default settings specified in your project.

Item

Description

Work offline

If this option is checked, Maven works in the offline mode and uses only those resources that are available locally.

This option corresponds to the --offline command line option.

Use plugin registry

Check this option to enable referring to the Maven Plugin Registry.

This option corresponds to the --no-plugin-registry command line option.

Execute goals recursively

If this option is cleared, the build does not recur into the nested projects.

Clearing this option equals to --non-recursive command line option.

Print exception stack traces

If this option is checked, exception stack traces are generated.

This option corresponds to the --errors command line option.

Always update snapshots

Select this checkbox to always update snapshot dependencies.

Output level

Select the desired level of the output log, which allows plugins to create messages at levels of debug, info, warn, and error, or disable output log.

Checksum policy

Select the desired level of checksum matching while downloading artifacts. You can opt to fails downloading, when checksums do not match --strict-checksums, or issue a warning --lax-checksums.

Multiproject build fail policy

Specify how to treat a failure in a multiproject build. You can choose to:

  • Fail the build at the very first failure, which corresponds to the command line option --fail-fast.

  • Fail the build at the end, which corresponds to the command line option --fail-at-end.

  • Ignore failures, which corresponds to the command line option --fail-never.

Plugin update policy

Select plugin update policy from the drop-down list. You can opt to:

  • Check for updates, which corresponds to the command line option --check-plugin-updates.

  • Suppress checking for updates, which corresponds to the command line option --no-plugin-updates.

Threads (-T option)

Use this field to set the -T option for parallel builds. This option is available for Maven 3 and later versions.

For more information, see parallel builds in Maven 3 feature.

Maven home directory

Use this list to select a bundled Maven version that is available (for Maven2, version 2.2.1 and for Maven3, version 3.0.5) or the result of resolved system variables such as MAVEN_HOME or MAVEN2_HOME. You can also specify your own Maven version that is installed on your machine. You can click the Browse button  and select the necessary directory in the dialog that opens.

User settings file

Specify the file that contains user-specific configuration for Maven in the text field. If you need to specify another file, check the Override option, click the ellipsis button and select the desired file in the Select Maven Settings File dialog.

Local repository

By default, the field shows the path to the local directory under the user home that stores the downloads and contains the temporary build artifacts that you have not yet released. If you need to specify another directory, check the Override option, click the ellipsis button and select the desired path in the Select Maven Local Repository dialog.

Common settings

When you edit a run configuration (but not a run configuration template), you can specify the following options:

Name

Specify a name for the run/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10.

Allow parallel run

Select 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, IntelliJ IDEA suggests to stop the running instance and start another one. This is helpful when a run/debug configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to 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.

By default, it is disabled, and IntelliJ IDEA stores run configuration settings in .idea/workspace.xml.

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Move into new folder / Create new folder

Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category, click Folder, and specify the folder name. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders or out of a folder, use drag or Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.
