The sole consumer in Nixpkgs of `releaseTools.antBuild` is
`pkgs/development/libraries/junit`, which has been broken since
2015-09-08. The sole consumer in Nixpkgs of `junit` is
`pkgs/development/libraries/junixsocket`, which hasn't built due to
`junit` since 2015-09-08. All three are removed due to their obvious
lack of use.
All other packages in Nixpkgs depending on junit consume
`pkgs/development/java-modules/junit`, which is not broken.
Any downstreams that have kept using these `junit` or `junixsocket`
packages since 2015-09-08 have basically already vendored the packages
via patching them, so no aliases are provided.
