unity-builder: JDK not found

Bug description

I just upgraded to Unity 2022.2.1f1 and game-ci/unity-builder@v2.1.2 The build for most platforms works fine.

Only Android build has issues because the JDK is not found:

2023-01-09T11:27:13.6923522Z DisplayProgressbar: Detect Java Development Kit (JDK)
2023-01-09T11:27:13.9736423Z UnityException: JDK not found
2023-01-09T11:27:13.9737808Z Java Development Kit (JDK) directory is not set or invalid. Please, fix it in Edit / Unity -> Preferences -> External Tools

2023-01-09T11:27:13.9745377Z UnityBuilderAction.Builder:BuildProject() (at Assets/Editor/Editor/UnityBuilderAction/Builder.cs:71)

In Preferences -> External Tools the check box is set for JDK installed with Unity (recommended).

I see Docker Hub has some images with android in its name. Do I have to use a specific image?

Expected behavior

The Docker image should include the JDK at the expected location.

Additional details

Please find the GitHub Actions yml configuration here and the program output here

So far, I just specified

...
        unityVersion:
          - 2022.2.1f1
        targetPlatform:
          - Android # does NOT work at the moment
          - iOS     # does work

It’s not a private discord or close circle in any way.

It’s actually the community (public) home. You can use this invite until someone fixes the url: https://discord.gg/ZjpyhCRd

Edit: Issue is fixed in https://github.com/game-ci/documentation/pull/374

TLDR: Unity has fixed it internally, we are waiting for hub to release 3.5. There are also additional steps needed like fixing the errors thrown by new hub versions due to gpu acceleration and if Unity doesn’t fix the sym link issue we need to bake the sym link fix into the images as well.

This is unity’s problem. Unluckily recent version has this bug. It’s not setting the correct JDK to the editor on installation. I faced this error one week ago, and there is no easy workaround.
