Could not compile initialization script eclipsePlugin.gradle: Unsupported class file major version 61

Today I started to get the following error on one of my workspaces. Any action involving Buildship fails with:

FAILURE: Build failed with an exception.

* Where:
Initialization script '/home/mauro/workspace/myworkspace/.metadata/.plugins/org.eclipse.buildship.core/init.d/eclipsePlugin.gradle'

* What went wrong:
Could not compile initialization script '/home/mauro/workspace/myworkspace/.metadata/.plugins/org.eclipse.buildship.core/init.d/eclipsePlugin.gradle'.
> startup failed:

I can’t really understand what is going on. Eclipse itself runs with Java 17. My buildscript is requesting Java 8. The error occurs while trying to compile a script (eclipsePlusing.gradle) which is not under my control. The error suggests Gradle is trying to parse some kind of JAR file (I don’t know which) which seems to be compiled using Java 17. But it can’t be one of my projects JARs or dependencies.

In the Gradle options I set it to use the Gradle wrapper defined in the build (which is 6.5.1). In the workspace I have JREs configured for Java 7, 8 and 11. I am being using such kind of workspace setup for months/years without problems and I currently do not have any problem on other workspaces and/or other Gradle projects. I even tried to trash away the workspace and re-create it from scratch, by using “Import Existing Gradle Project into Workspace”, but I get the error when trying to parse the build.gradle in the import wizard… :flushed:

I’m not sure which Java version Buldship is supposed to run its jobs with. I guess it should be using the Eclipse runtime one? If so, it should be using Java 17 and should not complain in this way.
I’m not forcing any JAVA_HOME in Window | Preferences | Gradle | Java Home.

Any hint on what should I look for to fix this?
Using Eclipse 2022-06 with Buildship 3.1.6.v20220511-1359.

Even if I force Gradle to use Java 17, through Window | Preferences | Gradle | Java home, or within the project properties, I still get the above error. This sounds even more weird…
