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 %classpath that 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 %classpath magic
%addMavenDependency is an alias to %maven. No reason to support this longer alias.
