> Make JSPC plugin useful to validation and analysys
> --------------------------------------------------
>
> Key: SLING-6925
> URL: https://issues.apache.org/jira/browse/SLING-6925
> Project: Sling
> Issue Type: Improvement
> Components: Maven Plugins and Archetypes
> Affects Versions: Maven JSPC Plugin 2.0.8
> Reporter: Tobias Bocanegra
> Priority: Minor
>
> the JSPs plugin is very useful to validate the JSPs before they get packaged
> into the artifact. --but the deployment unit might not need to class files
> but there is currently no way to disable their attachment--. further it might
> be valuable to know which dependencies in the project are really used by the
> JSPs. this helps developers to optimize the runtime dependencies of their
> code.
> suggest:
> - --add new flag: {{attachClasses}} (default true)--
> - analyze the java packages of the class path used to compile the JSPs and
> report which dependencies are not used.
> - add new flag: {{reportUnusedDependencies}} (default true)
> - add new flag: {{dumpClassPathUsage}} (default false)
