Run/Debug Configuration: Kotlin
The Kotlin run/debug configuration enables you running or debugging Kotlin applications.
The dialog box consists of the following tabs:
Specify the fully qualified name of the class to be executed (passed to the JRE). Type the class name manually or click to open the Choose Main Class dialog box, where you can find the desired class by name or search through the project.
Specify the string to be passed to the VM for launching an application, for example,
When specifying JVM options, follow these rules:
Type a list of arguments to be passed to the program in the format you would use on the command line. Use the same rules as for specifying the VM options.
Specify the working directory to be used for running the application. This directory is the starting point for all relative input and output paths. By default, the field contains the directory where the project file resides. To specify another directory, click and select the directory.
Expand the drop-down list to view available path variables that you can use as a path to your working directory.
Create environment variables and specify their values.
Use classpath of module
Select the module whose classpath should be used to run the application.
Include dependencies with 'Provided' scope
Enable this option to add dependencies with the Provided scope to the runtime classpath.
Shorten command line
| Select a method that will be used to shorten the command line if the classpath gets too long or you have many VM arguments that exceed your OS command line length limitation: |
Code Coverage tab
Use this tab to configure code coverage monitoring options.
Choose coverage runner
Select the desired code coverage runner.
Select this option to measure code coverage with minimal slow-down.
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 check box to detect lines covered by one test and all tests covering line. If this check box is selected, becomes available on the toolbar of the coverage statistic pop-up window.
Refer to the section : view JUnit tests that cover the line at caret. .
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 check box is selected, the folders marked as test are included in the code coverage analysis.
Log File Entry
The read-only fields in this column list the log files to show. The list can contain:
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.
When you edit a run configuration (but not a run configuration template), you can specify the following options for it:
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 (Shift+Alt+F10).
Select this checkbox 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
If the file-based format is used, the settings are stored in the
Allow running in parallel
When disabled, 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 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.
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.
Create a run/debug configuration.
Delete the selected run/debug configuration. Note that you cannot delete default configurations.
Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
View and edit the default template for the selected run/debug configuration. The templates are used for newly created configurations.
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-and-drop or and buttons.
To remove grouping, select a folder and click .
Click this button to sort configurations in the alphabetical order.
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:
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. |
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.
Click this icon to add one of the following available tasks:
Click this icon to remove the selected task from the list.
Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
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
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 Alt+4 or Alt+5.
