Hi all,

This may be a very stupid question, but I seem to be missing something
here: I've written a simple ANT workflow that uses some of the Epsilon
tasks. The ANT editor in Eclipse finds the tasks and happily offers them
and their parameters to me as part of its autocompletion. So, somehow,
they seem to be registered correctly. However, once I trigger the build
script using Run As/Ant Build, the build fails and ANT complains about
not finding the task definitions. Here's what it says:

...\build.xml:12: Problem: failed to create task or type
epsilon.emf.loadModel
Cause: The name is undefined.

I am using Epsilon from SVN, that is, I have one Eclipse instance in
which I have some of the Epsilon projects open (...workflow among them)
and from this start a second Eclipse instance which contains my actual
workflow. If I look at the launch configuration for my ANT script, it
actually doesn't refer to the workflow.jar file created as part of the
workflow project. I might be able to add this manually, but I assumed
this should happen automatically?

Cheers,

Steffen

As additional information: Checking the global Ant preferences and, in
particular, the 'Runtime' category, I find that workflow.jar is there
alright and all the Epsilon tasks are listed as well. I'm sure I'm doing
something wrong somewhere, but I have no idea where...

Any hints are appreciated!

Thanks,

Steffen

Mmh. It seems that this works OK when I tell it to run ANT in the same
VM as the IDE (which unfortunately is not the default). But why does it
not work when running in a separate VM?

Hi Steffen,

I have to admit I'm not quite sure either. I suspect it has something to
do with the (non) visibility of org.eclipse.epsilon.workflow.jar to the
new VM. Could you please open a bug so that we can track any further
investigation on this?

Cheers,
Dimitris
