Errors rose when a Netbean Maven Project tries to run
- by Zakaria
Hi everybody,
I installed NetBeans 6.8 on Vista and and I'm trying to execute a simple Maven Project.
When I ran the project, I got this set of errors:
WARNING: You are running embedded Maven builds, some build may fail due to incompatibilities with latest Maven release.

Theses exceptions rose even if I can run the database by using the console (ij) and when I connect the Database, no errors are showing.
Can you help me please?
Thank you very much.
