I\'m trying to create a very simple webapp with maven and eclipse, but I\'m having no joy at all, in fact the reverse of joy.
I go to File -> New Project, select Mav
I had the same problem even when i added JRE system library to my current java version but still had same problem then i just deleted JRE system library and added once again it worked for me
To delete JRE System Library right click on project ->properties ->java build path -> select JRE system library -> remove
To add JRE go to properties->java build path -> add library ->JRE system library -> choose JRE -> finish
