I discovered a "root" property in the build.properties caused this
issue. The value in it was wrong, leading to the exception.
This property was probably not supported in 0.12.

Hi,
I am moving GMF-Tooling build to from Tycho 0.12 to Tycho 0.13. I
use the Tycho-source-plugin to generate sources for my bundles,
and then I gather sources into a feature.
But here is the error I get when packaging the feature (with -X
flag):

I was not able to find the FeatureRootAdvice source code to see
which condition is failing.
Can anyone help me on this? Sources and build available here: https://hudson.eclipse.org/hudson/job/tycho-gmp.gmf.tooling/
Thanks in advance.
