Deprecate redundant magics: %jars, %addMavenDependency
There are few magics that we inherited from IJava that seem redundant that we are going to deprecate (and, eventually, remove)
%jars- this seems to be a more restricted version of%classpaththat only filter entries that are files, and skips directories. So it can be fully replaced by%classpath. So deprecation here will also internally route it to the%classpathmagic%addMavenDependencyis an alias to%maven. No reason to support this longer alias.
