Creating a custom run configuration using IntelliJ SDK and adding Build task in Before launch section

Question

I'm following the tutorial in Run Configuration section of IntelliJ IDEA SDK.

Following the tutorial, I will get a new configuration panel with an empty "Before launch" section. That section is added by default.

I would like to specify some targets by default, i.e. at least the Build target as done in several plugins (see next picture)

I'm trying to understand how, but I cannot find any example nor documentation on this.

How can I add default build task?

Your run configuration (DemoRunConfiguration in the example) should implement RunProfileWithCompileBeforeLaunchOption. This interface doesn't provide any methods to implement, so this is a kind of mark. build task will be added automatically, no additional steps are required.

How can I add my own task to before launch section?

Your plugin.xml should contain a line with stepsBeforeRunProvider

<stepsBeforeRunProvider implementation="com.MyBeforeRunProvider" id="myBeforeRun"/>

For that you should create "before run provider" with "before run task".

public class BeforeRunProvider extends BeforeRunTaskProvider<MyBeforeRunTask> {
    @Override
    public Key<MyBeforeRunTask> getId() {
        return Key.create("ThisIsId");
    }

    @Override
    public String getName() {
        return "Nice name";
    }

    @Override
    public String getDescription(MyBeforeRunTask task) {
        return "Description";
    }

    @Nullable
    @Override
    public Icon getIcon() {
        return AllIcons.Actions.Compile;
    }

    @Nullable
    @Override
    public MyBeforeRunTask createTask(@NotNull RunConfiguration runConfiguration) {
        return new MyBeforeRunTask(getId());
    }

    @Override
    public boolean executeTask(@NotNull DataContext dataContext, @NotNull RunConfiguration runConfiguration, @NotNull ExecutionEnvironment executionEnvironment, @NotNull MyBeforeRunTask myBeforeRunTask) {
        return true;
    }
}

And the task:

public class MyBeforeRunTask extends BeforeRunTask<MyBeforeRunTask> {

    protected MyBeforeRunTask(@NotNull Key<MyBeforeRunTask> providerId) {
        super(providerId);
        setEnabled(true);
    }
}
