Retiring the ANT/JAVA build and removing the older EDK II packages that required ANT/JAVA.
Last Ant/Java build was r7166
Developers requiring the Java/Ant packages should checkout the branch from:
https://edk2.tianocore.org/svn/edk2/branches/AntJava
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7168 6f19259b-4bc3-4df7-8a09-765794883524
