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
Code Coverage tab
Maven Settings tab

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 Running 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 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, becomes available on the toolbar of the coverage statistic popup. This option is only available for the Tracing mode of code coverage measurement for the testing run/debug configurations. Refer to the sectionConfigure code coverage options.
Packages and classes to record code coverage data	Click and buttons 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 button.
Enable coverage in test folders.	If this checkbox is selected, the folders marked as test 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 drop-down 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 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

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

Item	Description
Name	In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup `Shift+Alt+F10`.
Share through VCS	Select this checkbox to put the run/debug configuration under version control and make it available to other team members. If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise. If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.
Allow running in parallel	If this checkbox is selected, it is possible to launch a run configuration multiple times in parallel instead of rerunning it. Each runner will start in its own tab of the Run Tool Window or Debug Tool Window. When disabled, every time a new instance of the run/debug configuration is launched, IntelliJ IDEA checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog. If you click OK in the confirmation dialog, the first instance of the runner will be stopped, and the next one will take its place. This makes sense when launching two instances of run/debug configurations of the same type consumes too much of the CPU and memory resources..

Item

Description

Name

In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup Shift+Alt+F10.

Share through VCS

Select this checkbox to put the run/debug configuration under version control and make it available to other team members.

If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise.

If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.

Allow running in parallel

If this checkbox is selected, it is possible to launch a run configuration multiple times in parallel instead of rerunning it. Each runner will start in its own tab of the Run Tool Window or Debug Tool Window.

When disabled, every time a new instance of the run/debug configuration is launched, IntelliJ IDEA checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog. If you click OK in the confirmation dialog, the first instance of the runner will be stopped, and the next one will take its place. This makes sense when launching two instances of run/debug configurations of the same type consumes too much of the CPU and memory resources..

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.

Item	Shortcut	Description
	`Alt+Insert`	Create a run/debug configuration.
	`Alt+Delete`	Delete the selected run/debug configuration. Note that you cannot delete default configurations.
	`Ctrl+D`	Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
		The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
		View and edit the template (that is, the default run/debug configuration settings). The templates are displayed under the Templates node and used for newly created configurations.
/	`Alt+Up`/`Alt+Down`	Move the selected run/debug configuration up and down in the list. The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration. Default templates of run/debug configurations are always sorted alphabetically.
		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 , 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 and buttons. To remove grouping, select a folder and click .
		Click this button to sort configurations in the alphabetical order.
