gradle IntelliJ IDEA Task Customization Add a Basic Run Configuration

Example

Assumptions for this example:

• You have a class, foo.bar.Baz.
• You'd like to create a run configuration that runs the main method.
• It's in a module called fooBar.

In your gradle file:

idea {    
    workspace.iws.withXml { provider ->
        // I'm not actually sure why this is necessary
        def node = provider.asNode()    

        def runManager = node.find { [email protected]('RunManager')}

        // find a run configuration if it' there already
        def runner = runManager.find { it.find ({ mainClass ->
            return mainClass.@name != null && mainClass.@name == "MAIN_CLASS_NAME" && mainClass.@value != null && [email protected]('Baz');
        }) != null }

        // create and append the run configuration if it doesn't already exists
        if (runManager != null && runner == null){
            def runnerText = '''
                <configuration default="false" name="Baz" type="Application" factoryName="Application" nameIsGenerated="true">
                  <extension name="coverage" enabled="false" merge="false" runner="idea">
                    <pattern>
                      <option name="PATTERN" value="foo.bar.Baz" />
                      <option name="ENABLED" value="true" />
                    </pattern>
                  </extension>
                  <option name="MAIN_CLASS_NAME" value="foo.bar.Baz" />
                  <option name="VM_PARAMETERS" value="" />
                  <option name="PROGRAM_PARAMETERS" value="" />
                  <option name="WORKING_DIRECTORY" value="file://$PROJECT_DIR$" />
                  <option name="ALTERNATIVE_JRE_PATH_ENABLED" value="false" />
                  <option name="ALTERNATIVE_JRE_PATH" />
                  <option name="ENABLE_SWING_INSPECTOR" value="false" />
                  <option name="ENV_VARIABLES" />
                  <option name="PASS_PARENT_ENVS" value="true" />
                  <module name="foobar" />
                  <envs />
                  <method />
                </configuration>'''
            runner = (new XmlParser()).parseText(runnerText)
            runManager.append(config);
        }

        // If there is no active run configuration, set the newly made one to be it
        if (runManager != null && runManager.@selected == null) {
            runManager.@selected="${runner.@factoryName}.${runner.@name}"
        }
    }
}
