Re: [I] Maven Build Cache Extension incorrectly handles --module-version compiler arguments for Java modules, causing cache invalidation on every build despite no source code changes [maven-build-cache-extension]

   PR #389 implements default compiler property tracking that should help with this issue. The extension now tracks `source`, `target`, and `release` properties by default for maven-compiler-plugin.
   
   However, your specific case with `--module-version` in `compilerArgs` may need additional tracking. The current implementation doesn't include `compilerArgs` in the defaults to avoid overly aggressive cache invalidation. You may need to add:
   
   ```xml
   <executionControl>
     <reconcile>
       <plugins>
         <plugin artifactId="maven-compiler-plugin" goal="compile">
           <reconciles>
             <reconcile propertyName="compilerArgs"/>
           </reconciles>
         </plugin>
       </plugins>
     </reconcile>
   </executionControl>
   ```
   
   This would merge with the defaults and also track your `compilerArgs` containing `--module-version`.
