[jira] Created: (MNG-2860) Empty entry causes
OutOfMemoryError
Empty <module></module> entry causes OutOfMemoryError
-----------------------------------------------------
Key: MNG-2860
URL: http://jira.codehaus.org/browse/MNG-2860
Project: Maven 2
Issue Type: Bug
Components: Reactor and workspace
Affects Versions: 2.0.5
Environment: Windows XP SP2 with all available patches
Sun JDK 1.6.0
Reporter: Thorsten Heit
Priority: Minor
Accidentially I forgot to remove an empty <module></module> entry in my pom.xml. When I tried to fully clean my project and all its subprojects Maven crashes with an OutOfMemoryError after a couple of minutes:
H2841@YBPB055257 /cygdrive/d/workspaces/sukv-maven
$ mvn -e -X clean
+ Error stacktraces are turned on.
