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-commun…

Ran into this again with the plugin verifier. How is OpenProjectTask supposed to be used in 3rd-party plugins? The entry point to OpenProjectTaskBuilder is @Internal and pretty much everything else, even though there’s @PublishedAPI in the class.

Could you please tell us why do you need it? It is definitely not API for plugins

[image] Joachim Ansorg: PublishedAPI It has rather different meaning in Kotlin, it does not mean it is public API but enables some inline fun visibility tricks: /** * When applied to a class or a member with internal visibility allows using it from public inline functions and * makes it ef…

I’m implementing a com.intellij.projectImport.ProjectOpenProcessor. The implementation of openProjectAsync needs to return a Project and I couldn’t find any other way to create a new instance of a Project except with OpenProjectTask. As far as I can tell intellij-community is using the task for its…

We mostly delegate to PlatformProjectOpenProcessor.getInstance().openProjectAsync in newer implementations, which is public

[image] Yuriy Artamonov: PlatformProjectOpenProcessor.getInstance().openProjectAsync That method is @Internal if I’m not mistaken: platform/platform-impl/src/com/intellij/platform/PlatformProjectOpenProcessor.kt master @Internal override suspen…

This is a huge mistake, it should not be. As in ProjectOpenProcessor it is a normal public function. As a temporary workaround, you can cast instance to it

Fixes are on the way! https://youtrack.jetbrains.com/issue/IJPL-244518/PlatformProjectOpenProcessor.openProjectAsync-is-mistakenly-marked-ApiStatus.Internal

My colleagues also suggest using ProjectManagerEx.openProjectAsync directly, it is more correct. Please try in your ProjectOpenProcessor: ProjectManagerEx.openProjectAsync(Path.of("/home/user/some/project"), projectOpenOptions.toOpenProjectTask())

Thanks! As far as I understand, the options were only added a few days ago: IJPL-243183 propagate original OpenProjectTask from ProjectUtil.openO… · JetBrains/intellij-community@285ec88 · GitHub For now, I’ll have to use PlatformProjectOpenProcessor, I think.
