The code source repository of eXo Platform has moved from OW2 to its own tree located at the svn.exoplatform.org URL. Of course, we have just moved the source repository and binary downloads will always be available on OW2 forge. The move is done to improve performance for our remote teams in Ukraine and Vietnam.
To check out the code you just need a subversion client and the command:
svn co http://svn.exoplatform.org/svnroot/exoplatform/projects
