Jochen Stiepel commented on MNG-4798:
-------------------------------------
Sorry, for my short comment.
If I run mvn clean install I'll get MNG-4794
If I run mvn clean package I'll get MNG-4798 (this issue)
It is the same maven multiproject from within I call maven.
It ONLY happens with Maven 3 Beta-3 and NOT with Beta-2.
It ONLY happens on my Linux Server and not on my Windows Notebook. (Same Java
Version).
I don't have an example project currently.
What else can I do for you? Providing debug output?
I thought, maybe my Maven 3 Beta-3 installation (from tar.gz) is broken, but
I'll get the same error from another installtion out of the zip-archive.
What else can be plattform specific? Or can be corrupt on my Linux-Server?
I'll try to run it on another Linux-Installation to check it there.
