[jira] Commented: (MNG-2227) Can't use repositories in protocols
other than http
[ http://jira.codehaus.org/browse/MNG-2227?page=comments#action_63540 ]
Carlos Sanchez commented on MNG-2227:
-------------------------------------
Actually it doesn't fail due to the previous exception, it fails later when trying to download a jar wich is not in the repositories checked before the scm one.
