Hi Martin,
I agree with Achim. Since the file is physically present, the only
option I can think of is that the workspace isn't up-to-date and needs a
refresh.
One way to ensure a refresh is to issue a buckminster build on the
workspace. It stars with a full workspace refresh.
How is the workspace populated?

Hi Miles,

The launcher will use the Eclipse Resource name and not the filename when it locates the launch file. So instead of using
'features/org.eclipse.amp.build/org.eclipse.amf.acore.edit.t est.launch'
you should probably use:
'org.eclipse.amp.build/org.eclipse.amf.acore.edit.test.launc h'
or even perhaps:
'org.eclipse.amp.build-feature/org.eclipse.amf.acore.edit.te st.launch'
It all depends on what name the feature project has in the workspace.

Is it possible for me to set up this build? A bugzilla with some instructions on how to reproduce the problem would be
great.
