Hi,
I am following the tutorials in the sonatype Maven book
http://www.sonatype.com/book (Thumbs up). Chapter 4 and 5 worked perfect
under eclipse but when I try the project setup in chapter 6, which is
basically the same as chapters 4 and 5 but in a multi module, eclipse
starts to behave strangely. I am trying to run the tutorial under tomcat
(6.0.16) where I get a ClassNotFoundError for the tutorial servlet
classes (I cannot show it here because I cannot reproduce the error due
to the following issue). With jetty from the console (like in the
tutorial) it worked fine. After this, the simple-webapp submodule
project is broken. When I try Update Project Configuration I get an
error dialog showing the following message:
An internal error occurred during: "Updating Maven Configuration".
java.lang.NullPointerException
And this is the stacktrace in the workspace log
!ENTRY org.eclipse.core.jobs 4 2 2008-09-22 09:23:23.002
!MESSAGE An internal error occurred during: "Updating Maven Configuration".
!STACK 0

Deleting the eclipse files and hitting Update Project Configuration does
not solve the problem. I am using Eclipse 3.4.0, WST 3.0.0 and m2eclipse
0.9.6. Does anyone has a clue?
Cheers
