mvn compile does not start (CodeGenerationException)

[alpha-centauri]

I worked with the project in earlier versions and Java 8 in the past. Having switched to the current 5.1 branch of the Graylog2 server project and Java 17, I cannot compile anymore. Is Java 17 the correct java Version?

Maven throws the following errors:

~/project/graylog-project-repos/graylog2-server$ mvn compile
[ERROR] Error executing Maven.
[ERROR] java.lang.IllegalStateException: Unable to load cache item
[ERROR] Caused by: Unable to load cache item

Some more info on my dev environment:

$ mvn -version

@alpha-centauri please try with a newer mvn version. I think that should solve the issue.

Jan, you are right. It works with Maven 3.9.5. Thank you!
