Upgrade Android gradle plugin to 8.0.0 cannot let me select Java SDK

Question

I'm trying to upgrade my Android gradle plugin to 8.0.0.

It seems Android Studio has a bug and cannot let me select the Java SDK.

Or to be more precise, it lets me to select it but the "Run selected steps" button remains disabled/grey.

Also, the "Upgrade project JDK for running Gradle" bullet point still remains marked with an error.

See the screenshot below.

Is there any way to do this manually or something?

Thanks in advance.

EDIT: I've downloaded Coretto 20 and the error is still there.

EDIT 2: Haha it works with Corretto 17, BUT ONLY with 17 and not with 20

And after that, it fails again:

Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the User Manual chapter on the daemon at https://docs.gradle.org/8.0/userguide/gradle_daemon.html

Check the JVM arguments defined for the gradle process in:

Answer 1

As stated in the dialog, Gradle 8 requires JDK 17 and it seems you don't have it installed on your machine. To do so, you should click on "Download JDK...", select one of the available JDK 17 (for instance Corretto, Jetbrain etc) and restart the migration procedure.

Hope this helps

Answer 2

Just download it and install it from the Oracle site. Make sure to setup the path variables correctly depending on your system.
