Hello,

each time acceleo wants to build a file (e.g. new acceleo project wizard, clean of workspace) I get the following exception:

java.lang.NullPointerException
	at org.eclipse.acceleo.common.utils.ModelUtils.load(ModelUtils.java:386)

What can I do to resolve this? My script builds perfectly with maven.

Hello,

I am having the same problem. I am using Eclipse Luna M6 and Acceleo 3.5 that comes with it. It is a very annoying problem.

Somebody please help,

Thanks in advance,

Onder.

Hi

I've seen this too, but dismissed it as irritating but benign.
Uninstalling Acceleo of course solved the problem. I've re-installed
Acceleo and don't see the problem... yet. I'll keep my eye out.

You should find a stack trace in the error log, which should help the
developers to fix the problem.

Regards
