Run/Debug Configuration: MPS Instance

This run/debug configuration allows running a new MPS instance from within another MPS instance and thus debug it or see it working on an arbitrary project.

Item

Description

MPS system path

The location to store the MPS system data, defaults to the location used by the current MPS instance

MPS configuration path

The location to store the MPS configuration data, defaults to the location used by the current MPS instance

Virtual machine parameters

provide command-line arguments to the JVM

Alternative JRE path

Explicitly specify a JRE distribution to use for running the class

Open current project

Indicate whether the new MPS instance shall open the project that is open in the current MPS instance

Project to open

Specify a project to open in the newly started MPS instance

Plugins to deploy

Choose plugins to make available in the newly started MPS instance

Common options

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

Item

Description

Name

In this text box, 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 (N/A).

Share

Select this checkbox to make the run/debug configuration available to other team members.

The shared run/debug configurations are kept in separate xml files under .idea \runConfigurations folder, while the local run/debug configurations are kept in the .idea\workspace.xml.

Allow running in parallel

When disabled, every time a new run/debug configuration is launched, MPS 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 checkbox is selected, it is possible to launch as many instances of the run/debug configuration as required. So doing, each runner will start in its own tab of the Run Tool Window or Debug Tool Window.

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

icons general add svgN/A

Create a run/debug configuration.

icons general remove svgN/A

Delete the selected run/debug configuration. Note that you cannot delete default configurations.

Copy

N/A

Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.

Edi Templates

Edit Templates

View and edit the default template for the selected run/debug configuration. The templates are used for newly created configurations.

icons actions moveUp svg/icons actions moveDown svg

N/A/N/A

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

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-and-drop or Move Up and Move Down buttons.

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

Sort configurations

Sort configurations

Click this button to sort configurations in the alphabetical order.

Templates

Under the Templates node in the tree view of run configurations, you can select a run configuration template and edit its default settings. This will not affect the configurations that are already created, but will be used as defaults when creating new configurations of the corresponding type.

When you select the Templates node itself, you will be able to adjust general settings that apply to all run/debug configurations:

Description

Configurations available in Run Dashboard

In this section you can create a list of run configurations available in the Run Dashboard — a tool window that helps you execute and manage multiple run/debug configurations.

Note that the dashboard will only display the configuration types for which you have created one ore more configurations.
Thus, if you add a configuration type for which no configurations exist in the project, this type will not be displayed on the dashboard until you create a configuration of this type.

Confirm rerun with process termination

The behavior of this checkbox depends on whether the Single instance only option is selected for a particular run/debug configuration.
  • If this checkbox is selected, in case of a single instance, launching a new process (for example, by clicking Run on the main toolbar) while another process is still running, results in showing a dialog box prompting to terminate the current process before launching a new one.

  • If this checkbox is not selected (or in case of multiple instances), MPS starts the new process silently.

Temporary configurations limit

Specify the maximum number of temporary configurations to be stored and shown in the Select Run/Debug Configuration drop-down list.

Before Launch options

In this area you can specify tasks that must be be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

Shortcut

Click this icon to add one of the following available tasks:

  • Run Another Configuration: select to execute another run/debug configuration. In the dialog that opens, select the configuration to be run.

Click this icon to remove the selected task from the list.

Edit

Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.

icons actions moveUp svg/icons actions moveDown svg

N/A/N/A

Click these icons to move the selected task one line up or down in the list. (The tasks are performed in the order that they appear in the list.)

Show this page

Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.

Activate tool window

If this checkbox is selected, which it is by default, the Run or the Debug tool window opens when you start the run/debug configuration.

Otherwise, the tool window isn't shown. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing N/A or N/A.
