IntelliJ IDEA 2021.2 Help

Run/Debug Configuration: Maven

This run/debug configuration is used to launch the Maven projects. The dialog contains the following tabs:

Item

Description

Name

In this field, specify the name of the current run/debug configuration.

Parameters tab

Item

Description

Working directory

Specify the path to the Maven project file pom.xml.

Command line

Specify the Maven goals and options separated with space.

Profiles

Specify the profiles to be used separated with space.

Resolve Workspace Artifacts

We recommend that you use this checkbox if you have dependent modules in your project.

By default, this checkbox is not selected. In this case, classes of dependent modules are searched in .jar files in a Maven local repository. If you select this checkbox, the classes of the dependent modules will be searched in the module compilation output. In this case, each time you make changes to the dependent module, you don't need to deploy them into a local repository.

General

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.

Runner tab

Item

Description

VM Options

Specify the string passed to the VM for launching the Maven project.

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}

JRE

Select JRE from the list.

Skip tests

If this option is checked, the tests will be skipped when running or debugging the Maven project.

Environment variables

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

Item

Description

Is Active

Select checkboxes in this column to have the log entries displayed in the corresponding tabs in the Run tool window or Debug tool window.

Log File Entry

The read-only fields in this column list the log files to show. The list can contain:

  • Full paths to specific files.

  • Ant patterns that define the range of files to be displayed.

  • Aliases to substitute for full paths or patterns. These aliases are also displayed in the headers of the tabs where the corresponding log files are shown.

    If a log entry pattern defines more than one file, the tab header shows the name of the file instead of the log entry alias.

Skip Content

Select this checkbox to have the previous content of the selected log skipped.

Save console output to file

Select this checkbox to 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 standard output stream

Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.out.

Show console when a message is printed to standard error stream

Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.err.

Common settings

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

Item

Description

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.

Item

Shortcut

Description

the Add button

Alt+Insert

Save configuration

The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.

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.

Sort configurations

Click this button to sort configurations in the alphabetical order.
