How can I use OpenProjectTask?

IntelliJ Platform
1

I’m trying to implement a ProjectOpenProcessor.

As far as I understand, I’m supposed to call com.intellij.openapi.project.ex.ProjectManagerEx#openProjectAsync in openProjectAsync. This needs a OpenProjectTask, but pretty much everything of OpenProjectTask is internal or restricted.

intellij-community is invoking a builder closure, which is @Internal, too:

@Internal
inline fun OpenProjectTask(buildAction: OpenProjectTaskBuilder.() -> Unit): OpenProjectTask {
  return OpenProjectTaskBuilder().build(buildAction)
}

For example, I want to value to OpenProjectTask.projectRootDir, which itself is @Experimental. But the constructor is @Internal, I can’t instantiate the builder because of internal `@Internal
inline fun OpenProjectTask` and so on.

How is this API supposed to be used by 3rd-party plugins?
