Description

Co-worker ran into issues where if he had checked out his project directly in his root dir C: (top pom ending up in C:\project\pom.xml) and ran the release:prepare goal he would rather quickly recieve this error:

I looked into it and eventually had him add a "buffer directory" so his top pom was resting in C:\workspace\project\pom.xml and following this move it built properly. Not sure if there is a real requirement to have this buffer directory, but a better error message would be helpful.
