- delete the project from the workspace
- Opens terminal and cd to the project directory (when the pom.xml is).
- rm -rf .settings .project .classpath
- Do (1)-(3) for any internal project my webapp project depends on.
- Import it again.
Which Eclipse are you using? Try Eclipse 3.6 and the latest m2eclipse.
Solves problems also.

Hi, I am getting an error (exception at bottom) and as result, the
project is almost correctly imported but Web Resources points to the
root project folder instead of src/main/webapp as default. I'll also
paste the pom.xml as reference, as far as I see, there is nothing
strange but some dependencies declared under maven-antrun-plugin which
I am not sure why they are there but does not seem related to the
problem to me.
Thanks.
