unfortunately the bug is not completely consistent

but with the latest Gemoc studio with latest melange, installing the official sample sometimes fails with the following errors: fr.inria.diverse.melange.resource.MelangeDerivedStateComputer - Fatal exception

additionally,
the inherits fails to find the other language (see screenshot)
and strangely, the plugins dependencies seems to be broken because despite that the manifest declares org.eclipse.gemoc.sample.legacyfsm.fsm, the project doesn't import it (see "Plug-in Dependencies" entry in the project tree)

Workaround:

  • rename the melange file (/org.eclipse.gemoc.sample.legacyfsm.xsfsm/src/org/eclipse/gemoc/sample/legacyfsm/xsfsm/language/XSFSM.melange) with another extension. (I used XSFSM.melange2 )
  • Restart eclipse (I've found no way to fix it without restarting eclipse); The org.eclipse.gemoc.sample.legacyfsm.fsm should now appear in the Plug-in Dependencies
  • rename back the melange file with the proper melange extension

this problem sounds like an issue about the order in which the tools are called in the builder (xtend/xext builder )

* studio in using oxygen.2
* improve jenkins file

- keep only one artefact per branch*
- set periodic pipeline check

* tee stdout and stderr to for the standard output and  to console

see #49

* add helper.setTargetPlatform in test that fail randomly
* add launch conf in order to ease test devs
* disable concurrent builds
