CWM Model generation with MDR-Ant error

[Tobias Mueller-2]

Hi!

I'm completely new to MDR, so please forgive me if I ask a stupid
question. I was trying to create a CWM MDR model from the OMG XMI files
plus the Diff to that I found on the MDR homepage with MDR-standalone. I
used the sample.xml buildfile for MDRant
(http://mdr.netbeans.org/unbranded-source/browse/~checkout~/mdr/extras/mdrant/sample.xml)
and updated it in the following way to adhere my local config and folder
structures:

<?xml version="1.0" encoding="UTF-8"?>

If I run this with ant, I get the following error:

BUILD FAILED
D:\Privat\Development\MDR\build.xml:44: mycwm does not exist in extent
mof4models

If I omit the second instanciate from the buildfile, the build works,
but I think then the CWM is not instanciated. I also was able to
successfully run the UML 1.4 files without error, only the CWM keeps me
puzzled. What would be the correct setting for CWM in this part:

<instantiate
               name="mycwm"
               extent="mof4models"
               package="mycwm"/>

Thanks a lot in advance,
Tobi
