As part of our policy, http://gentoo-wiki.com/Gentoo_Java_Policy/ we require that all .jar files are built entirely from source code whenever possible. Among other things, this means that a package is not allowed to install "bundled" jar files, such as junit.jar, xml-apis.jar, etc. Rather, they should add these libraries in their RDEPENDS, and use java-pkg_jar-from to set up the build environment before invoking ant (or whatever other build tool is in use). The typical procedure for removing bundled jars is: 1) ebuild dev-java/<packagename>/<packagename>-<version>.ebuild unpack 2) (As root) Inspect /var/tmp/portage/<packagename>/work/ for .jar files 3) Create or modify the src_unpack in the ebuild to 3.1) Remove all bundled .jar files by rm <list-of-jarfiles> 3.2) Install symbolic links for the required jars using java-pkg_jar-from 4) Update the RDEPENDS to ensure the require libraries are available to java-pkg_jar-from 5) Recompile and test that everything works. 6) Submit a patch for the ebuild.
