Embedded error: roots differ error on simple project

Jorg Heymans added a comment - 30/Sep/08 2:31 AM actually, there might be something environment specific here that is causing the exception. When i execute the first command again, but now from plain DOS i get something else: D:\tmp\reactor-bug\root-pom>mvn reactor:make -Dmake.artifacts=B-api [INFO] Scanning for projects...

Dan Fabulich added a comment - 30/Sep/08 1:22 PM Yes, it seems very likely that cygwin is causing the problem. The "plain DOS" results ("Cannot execute mojo: resources") are what I see on my machine also, and is what I would expect due to MREACTOR-1 . I'll try to repro the problem on cygwin.

Juan Cruz Nores added a comment - 19/Oct/10 4:37 PM I'm having the same problem on OSX, so I'm not so sure that it's environment-specific: + Error stacktraces are turned on.
