--------------------------------------------------------------
It seems that Beta3 introduced the following problem:
If I try to import a maven jar project that uses gwt-maven-plugin to generate async interfaces for RPC services (generateAsync goal) an error message appears saying that:

An internal error occurred during: "Updating Maven Configuration".
assertion failed: No web content folder was found in project gwt-utility-example

If I then try to manually add the target/generated-sources/gwt folder to the build path (which isn't done automatically, but that's another story I suppose) Eclipse complains that

Project configuration is not up-to-date with pom.xml. Run project configuration update

Trying to quick-fix this problem removes the target/generated-sources/gwt folder from the build path.

Here's my pom.xml (the complete project is attached):
