Description Sven Efftinge

When importing the gradle project https://github.com/eclipse/xtext/blob/master/separate-builds/core/build.gradle 
I get this exception:

Java Model Exception: Java Model Status [Cannot nest 'org.eclipse.xtext.ide/src' inside 'org.eclipse.xtext.ide'. To enable the nesting exclude 'src/' from 'org.eclipse.xtext.ide']
	at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation(JavaModelOperation.java:785)

I can manually fix it by adding the exclude, but the whole import is interrupted and thus incomplete.
Would be cool to
a) add proper excludes/includes as described in https://github.com/eclipse/xtext/blob/master/separate-builds/core/gradle/eclipse-project-layout.gradle
b) catch such exceptions generally, so I don't end up with a partially imported project

I am using the latest milestone build.
