Build error in eclipse

Question

I am using eclipse HELIOS. I am getting the following error message whenever I build my project.

Has anyone else experienced such error? Is it a problem of eclipse or the project? It never occured to me before but for this project its happening. It says NullPointerException but that should not pop up such message.

Please help, its driving me nuts. I need to check in my codes but I cant test them due to this building error.

Let me know if more details is reqd.

Answer 1

I found the solution. It was a maven plugin issue. Cleaning up the repository solved it.
