Run/Debug Configuration: Maven

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

Parameters tab
General tab
Runner tab

This section provides descriptions of the configuration-specific items, as well as the toolbar and options that are common for all run/debug configurations.

Item	Description
Name	In this text box, 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 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.

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 drop-down list.
Skip tests	If this option is checked, the tests will be skipped when running or debugging the Maven project.
Environment variables	Click Browse to open the Environment Variables dialog box, where you can create variables and specify their values.
Properties	Specify the properties and their values to be passed to Maven.

Logs tab

Use this tab to specify which log files generated while running or debugging should be displayed in the console, that is, on the dedicated tabs of the Run or Debug tool window.

Item	Description
Is Active	Select check boxes 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 check box to have the previous content of the selected log skipped.
Save console output to file	Select this check box 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 check box 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 check box to activate the output console and bring it forward if an associated process writes to Standard.err.
	Click this button to open the Edit Log Files Aliases dialog where you can select a new log entry and specify an alias for it.
	Click this button to edit the properties of the selected log file entry in the Edit Log Files Aliases dialog.
	Click this button to remove the selected log entry from the list.

Toolbar

Item	Shortcut	Description
	`Alt+Insert`	Click this button to add a new configuration to the list.
	`Alt+Delete`	Click this button to remove the selected configuration from the list.
	`Ctrl+D`	Click this button to create a copy of the selected configuration.
	Edit defaults	Click this button to edit the default configuration templates. The defaults are used for newly created configurations.
or	`Alt+Up` or `Alt+Down`	Use these buttons to move the selected configuration or folder up and down in the list. The order of configurations or folders in the list defines the order in which configurations appear in the Run/Debug drop-down list on the main toolbar.
	Move into new folder / Create new folder	Use this button to create a new folder. If one or more run/debug configurations are in focus, the selected run/debug configurations are automatically moved to the newly created folder. If only a category is in focus, an empty folder is created. Move run/debug configurations to a folder using drag-and-drop, or the buttons.
	Sort configurations	Click this button to sort configurations in alphabetical order.

Common options

Item Description

Name In this text box, specify the name of the current run/debug configuration. This field does not appear for the default run/debug configurations.

Defaults This node in the left-hand pane of the dialog box contains the default run/debug configuration settings. Select the desired configuration to change its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.

Select this check box to make the run/debug configuration 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.

This check box is not available when editing the run/debug configuration defaults.

Single instance only

If this check box is selected, this run/debug configuration cannot be launched more than once.

Every time a new 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 box. If you click OK in the confirmation dialog box, the first instance of the runner will be stopped, and the next one will take its place.

This makes sense when the usage of certain resources can cause conflicts, or when launching two run/debug configurations of the same type consumes too much of the CPU and memory resources.

If this check box is not selected, it is possible to launch as many instances of the runner as required. So doing, each runner will start in its own tab of the Run tool window.

Before launch

Specify which tasks must be performed before applying the run/debug configuration. The specified tasks are performed in the order they appear in the list.
