[ http://jira.codehaus.org/browse/MNG-2509?page=comments#action_75030 ] Antoine Levy-Lambert commented on MNG-2509: -------------------------------------------
Hello Davy, this problem might be due to Ant, not to Maven. It looks like it Ant's bug 40238 which is fixed in Ant 1.7. You can download Ant 1.7.0Beta2 from ant.apache.org to check whether this solves your issue.
