m2eclipse error

Question

I am developing a web application with Eclipse and I generate the project with a maven archetype.

When I enable maven dependency management, Eclipse mark some errors

Answer 1

This error bothered me for two days. I tried all kinds of solutions, nothing worked. Finally I give up and tried a radical approach. and it worked! Here are the steps:

1. Save a copy of the pom.xml,
2. deleted all text in pom.xml
3. Let eclipse do a clean rebuild, of course everything will be broken.
4. pasted back everything in the original pom.xml
5. let Eclipse build again

I guess it was "indeterministic" as the following article said.
