Tibor Digana edited comment on SUREFIRE-1132 at 12/29/14 7:15 AM: ------------------------------------------------------------------ Set trimStackTrace=false and retry. I would like to see full stack in reports. It still looks like jvm issue. Send the zip archive with erroneous project including target and sources. The ideal situation would be to reproduce it on our side. Does file:/d:/.m2/repository/junit/junit/4.11/junit-4.11.jar exist and the RunListener class exists inside? You can alternatively delete junit/4.11 folder in local repo and let the Maven download it again. Opened jvm sources UrlClassLoader@366 and the class is not found as resource, ie. Resource res = ucp.getResource(path, false); is null. was (Author: tibor17): Set trimStackTrace=false and retry. I would like to see full stack in reports. It still looks like jvm issue.
