Description

This seems to be similar to https://issues.apache.org/jira/browse/COCOON-2007.

I created two cocoon blocks and a webapp like this:

webapp
block1
block2

Then, I created a parent pom that referes to these modules in order to be able to build all at once. But when I execute "mvn install" within my parent project, I got this error:

Deleting the whole maven repo and downloading all plugins and dependencies again didn't work.

Changing the version of the mvn-war-plugin to 2.1-alpha-1 as suggested here (http://www.nabble.com/Creating-a-parent-POM-td18173518.html) worked, but is it right to depend on a alpha version?
