[QVTo] Standalone execution [message #807941]

Hi

A few earlier threads suggest some problems but ultimately success when
running a QVTo transformation standalone, but also some ambiguity about
quite what standalone means.

Does anyone know how to run a QVTo transformation when the Eclipse
platform is not running; i.e. no IFiles and no plugin registries?

It appears that DeployedQvtModule supports execution from a plugin and
that WorkspaceQvtModule supports execution from an IFile, but where is
the support for execution from a standalone Resource?

Regards

Hi All

It's pretty easy; just use org.eclipse.m2m.qvt.oml.TransformationExecutor.

Only minor trick is to provide positionally aligned ModelExtents with a
probably empty output one, whose contents need to be copied to an output
resource and saved on completion.

An MWE2 integration may soon be found at:
/org.eclipse.ocl.examples.build/src/org/eclipse/ocl/examples/build/utilities/QvtoWorkflowComponent.java

Ed,

Have you got QVTO running outside of OSGi (i.e. in a Java static void
main?) or is it just outside of Eclipse but within Equinox? I ran into
headaches getting things like blackbox units and transformation units
to compile when I tried this a while ago as a plain old java runtime,
but I've been successfully running it with a light-weight OSGi kernel.

Hi Alan

I'm running within the MWE2 environment for which
EMFPlugin.IS_ECLIPSE_RUNNING is false.

I have my own ProjectMapSetup to fully populate platform:/resource/...
and platform:/plugin/... from the class path. See
https://bugs.eclipse.org/bugs/show_bug.cgi?id=360926#c7 for my analysis
of what's needed to make standalone work.

Regards
