[Acceleo 3 / Helios] Cannot lauch transformation [message #634368]

I tried to use Acceleo mtl generator on Helios, but transformation hangs up on "Launching Delegate".

I thought it was a metamodel or mtl problem, so I used the very simple metamodel and very simple mtl below (sorry for huge context).
When I launch acceleo configuration after setting target directory, the execution process hangs at "Launching Delegate".
There's no entry in log, nor problem. I cannot stop the process, I must stop eclipse.

I Guess it is an Helios configuration problem, but I can't figure which.
Is there some test to check if an Eclipse Installation is OK to run Acceleo 3 ?

Thank you for your help

Metamodel :

  <?xml version="1.0" encoding="UTF-8"?>
  <ecore:EPackage xmi:version="2.0"
      xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="cv"
      nsURI="http://mymodel" nsPrefix="cv">
    <eClassifiers xsi:type="ecore:EClass" name="Experience" abstract="true">
      <eStructuralFeatures xsi:type="ecore:EAttribute" name="text" lowerBound="1" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
    </eClassifiers>
    <eClassifiers xsi:type="ecore:EClass" name="CV">
      <eStructuralFeatures xsi:type="ecore:EReference" name="categories" upperBound="-1"
          eType="#//Experience" containment="true"/>
    </eClassifiers>
  </ecore:EPackage>

generate.mtl :

  [comment encoding = UTF-8 /]
  [module generate('http://mymodel')/]

  [template public generate(c : CV)]
    [comment @main /]
    [file ('output.txt', false, 'UTF-8')]
      [for (ex : Experience | c.categories)]
        [ex.text/]
      [/for]
    [/file]
  [/template]

source model :

  <?xml version="1.0" encoding="UTF-8"?>
  <cv:CV xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cv="http://my.cv_auto/cv/1.0.1.test">
    <categories xsi:type="cv:Experience" start="" text="text" job=""/>
    <categories xsi:type="cv:Experience" text="text2"/>
  </cv:CV>

Hi buddy !!!
The second time I overpost myself this week (understand, I reply my own post)...

I succeeded in running the transformation doing this :

Start with Helios-Modeling-including incubation release
Install Acceleo 3 from http://download.eclipse.org/modeling/m2t/updates
Import the metamodel, and run it in a new Eclipse (only the metamodel, not Edit nor Editor)
In this new eclipse, run the genretation described before : It works

Conclusion : the problem comes form edit and Editor plugin (generated from metamodel automatically) and, I suppose, the dependencies installed to run these plugin. I don't know how to list exactly the intallation history.

How can I precisely list installation difference (not with GUI, because it makes it hard to copy the difference in plugin version this way). ?
Shall I open a bug ?
Is it an EMF problem or an Accelo ones ?

Anyway, as I'm the only one replying this thread, I'll post my discoveries as soon as I discover them.

Hi Cedric,

I have never observed "hanging" transformations ... and the use case
you've tried seems basic enough not for anything strange to happen.
There wasn't anything in your error log when you tried these (In Eclipse
: Window => Show View => Error Log)? Were you trying to generate in the
same Eclipse instance as where your metamodel is defined?

If "yes" to the latter, the problem you had might come from that, we
have various issues with generation on dynamic metamodels ("dynamic"
being metamodels located in your workspace as opposed to "plugin" with
your metamodels deployed as plugins of the instance of Eclipse you are
running the transformation from).

Hi laurent

First of all, thank you for your answer, it becomes rare on eclipse forum.

I'm very frustrated, and angry, to tell you that I cannot reproduce the bug... But I know there was no error log. I guess, by now, that the problem was related to the importation of an ecore model/edit/editor from a 3.5.1 version of eclipse. But As I cannot reproduce, I'm not sure of it. I completely recreated the model/edit/editor with Helios, and it worked fine.. !?!

I go on with my model, and will reply on this post if I face this problem again.

Best Regards

Hi Cedric,

I'm quite surprised by your first comment as I know most teams try to
maintain a good level of support on these forums (at least for the
EMF-related forums I read).

As for the bug, please do tell us if you manage to reproduce it, but as
I mentionned we never observed it ourselves, might have been bad luck :p.

I'm pretty sure I've seen it too, but I suspect that it's all part of
the very occasional failures of JDT to build projects/update build paths
correctly.
