Maven build error on startup

Hi,

Whenever I open IDEA and it opens my last open project, which is a Maven project it prints the error messages appended to the end of this post in the "Message Generating sources" window.

However, when I build the project afterwards by selecting compile from the Maven Projects windows, it builds my project with no problem. Any ideas why is this happening? I have already enabled 'Print Exception Stack Traces'.

I have temporarily fixed this by unchecking "Automatically generate sources and ... on import." Is this even a bug?

there's something strange, the compile phase of the maven lifecycle is not executed but the compiler is still launched ?
What's your pom like ?

IDEA tries to generate sources, etc. while my project does not require any sources or resources to be generated at all.
