Hi @mathewm3 , I’d like to work on this issue. From the error trace, it looks like AbstractNonCacheableEnforcerRule was introduced in a newer Enforcer version, causing a mismatch with the dependencies here. I’ll look into the version compatibility between maven-enforcer-plugin, extra-enforcer-rules, and linkage-checker-enforcer-rules to resolve the missing class issue.
Could you please assign this issue to me?
