Hello,
i'm totally new to Epsilon, so i started out with the examples to get first impression. I'm particularly interested in the M2M transformation so I downloaded the Tree2Graph example. However, I was not able to run the transformation on my machine because I got some strange behavior of the ANT script. Here is the console output:

I followed all instructions to setup the example:
1. Registering the .ecore metamodel is the metamodel project
2. setting ANT to run in the same JRE as ecilpse
3. invoking the ANT script
It gets very strange, when the ANT Task is invoked twice, then the console shows the following output:
Buildfile: /Users/henning/Downloads/org.eclipse.epsilon.examples.tree2g raph/launch.xml
loadModels:
main:
BUILD SUCCESSFUL
Total time: 261 milliseconds
I'm running the latest version of Epsilon and Eclipse Helios on Mac OS 10.6.4.
What did I do wrong?

Hi Henning,
I'm afraid I can't reproduce this on my Mac. I've checked out the two
projects, ran the launch.xml ANT file and everything worked as expected.
Are you using the stable or the interim version of Epsilon?
Cheers,
Dimitris

Hi Henning,
Yes. It fixes several bugs and will shortly be released (with very few
changes) as the next stable version (0.9).
Cheers,
