Build broken (Gradle version and JAVA updates) #350

Closed AntoniusW closed 1 year ago

AntoniusW commented 1 year ago

It appears that merging #349 broke our CI builds.

After pushing the new branch "ruleatom_nostring" (based on current master), the CI build immediately fails, see: https://github.com/alpha-asp/Alpha/actions/runs/3822262718

The error message is:

Could not compile initialization script '/home/runner/.gradle/init.d/build-result-capture.init.gradle'.
> startup failed:
  General error during conversion: Unsupported class file major version 63

According to https://docs.gradle.org/current/userguide/compatibility.html Java 19 is only supported after Gradle version 7.6 while we currently run at 7.3.2 for the CI builds.

Interestingly, the build job for #349 apparently succeeded with the Java 19 run throwing some exceptions but still succeeding: https://github.com/alpha-asp/Alpha/actions/runs/3668635491/jobs/6201900714

It appears that the currently failing branch tried to start with Java 19 and failed while the CI run for #349 used Gradle caching to obtain the already compiled Gradle build system. Could this have something to do with Gradle's caching?

From the top of my head, I'd say the best and easiest fix for this is to bump the gradle version to 7.6. I'll take care of that tonight.

Sorry about that. Super weird that #349 did build green.
