A current problem with brew version is that the source attachments in the repository are not usable by eclipse: [starksm@succubus repository.jboss.com]$ ls javassist/3.5.0.CR1-brew/src/ CVS/ javassist-3.5.CR1-src.tar.gz eclipse can only deal with source directories and jar/zip archives of source. This breaks the jbossas eclipse project sourcepaths that point to the thirdparty location for javassist-src.jar as it existed in the non-brew version: [starksm@succubus repository.jboss.com]$ ls javassist/3.5.0.CR1/lib/ CVS/ javassist.jar* javassist-src.jar [starksm@succubus repository.jboss.com]$ Inclusion of the version in the artifact also means the source attachment has to be updated every time there is a version change to the jbossas project.
