Noticed after updating to the latest that I had yet another error. This time, doing a maven project update it said it couldn’t update the Dynamic Web Module to 2.5 and it showed it set at 3.0. Our projects are set up for 3.0.
Unfortunately, I don’t remember which sites I got this tip from, but … what did to fix it was pretty straight-forward. Just right-click and bring up the project properties; select Project Facet and deselect the Dynamic Web Module; click okay to exit the dialog. Now re-run the maven “Update Project” and you’ll see the error disappear. Checking the Project Facets, you’ll see the Dynamic Web Module set to the proper version (2.5, in my case).
