Run/Debug Configuration: Java Scratch
Use the Java Scratch run/debug configuration to run and debug Java scratch files that have the
main() method defined.
|Main class||Specify the fully qualified name of the class to be executed (passed to the JRE).|
|Path to scratch file||Specify the path to the scratch file, or select one from the file chooser.|
Specify the string to be passed to the VM for launching an application, for example,
When specifying JVM options, follow these rules:
|Program arguments||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 list to view available path variables that you can use as a path to your working directory.
Create environment variables and specify their values.
|Redirect input from||Read input from the specified text file.|
|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:
|JRE||By default, the project JDK is used to run the application. If you want to specify an alternative JDK or JRE, select it from the list.|
When you edit a run configuration (but not a run configuration template), you can specify the following options:
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.
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.
|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.|
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.|
In this area you can specify tasks that must 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:
|Alt+Delete||Click this icon to remove the selected task from the list.|
|Enter||Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.|
|/||Alt+Up/Alt+Down||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, if the checkbox is cleared, the tool window is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
