Some software requires more than just move, copy, unzip, etc. in the packager resolver build instructions to build the software. E.g., Javadoc can only be constructed by building it with ant.
Request extending packager resolver to support arbitrary build instructions. Do this via a new "restricted" configuration attribute, which when true (the default) reproduces the existing behavior, but when false, allows arbitrary ant tasks in the build instructions.
See attached patch for proposed implementation and documentation updates.
