Attach source code to plug-in: Modeling Workflow Engine 2 Launch [message #1765600]

Hello,

Disclaimer: I am totally new to Eclipse, OSGi, EMF and xtext so please forgive my naive question and read past my inappropriate terminology.

TL;DR: How do I find and attach source code to a plug-in dependency in eclipse? Namely: org.eclipse.emf.mwe2.launch_2.9.0.v201605261103.jar.

We have started on an xtext project where we have defined a grammar, scoping, formatting and code generation - following guides all the way. However the time has come for us to dive deeper into the guts of xtext to see how it all 'hangs-together' and I wanted to start by examining how the mwe2 workflow is run.

With my default Eclipse Modelling Tools installation, I have a plug-in dependency: org.eclipse.emf.mwe2.launch_2.9.0.v201605261103.jar. Inside this lives Mwe2Runner.java. However I cannot find how to attach the source code to this jar. I can't quite see how the installed software components map to my plug-in dependencies i.e. given the above jar, which update site do I need to use and which software component (i.e. name) do I need?

As I'm new to the ecosystem, I'm not sure if this is a question of understanding xtext, eclipse or OSGi more generally so any guidance is appreciated.

Many thanks in advance.

Jim

When developing plugins you will have to set a target platform in Eclipse. This target platform has to include source bundles, which is usually bundled with SDK features.

If you have created a target definition with the Xtext wizard, add org.eclipse.emf.mwe2.launch.source.

<location includeAllPlatforms="false" includeConfigurePhase="false" includeMode="planner" includeSource="true" type="InstallableUnit">
<unit id="org.eclipse.emf.mwe2.launcher.feature.group" version="0.0.0"/>
<unit id="org.eclipse.emf.mwe2.launch.source" version="0.0.0"/>
<repository location="http://download.eclipse.org/modeling/emft/mwe/updates/releases/2.9.0/"/>
</location>

Thanks for the suggestion. I tried following, but no luck, here is what I did:

1. I started an xtext project from scratch to experiment with the target definition.
2. I created a target-definition.target file (location per screenshot 1).
3. I then edited the file adding your suggestion, however the 'Locations' section of the Target Editor is complaining (per screenshot 1).
4. I proceeded anyway and hit 'Set as Target Platform', but still no source files i.e. org.eclipse.emf.mwe2.launch.runtime.Mwe2Runner is still missing source files.
5. I updated <unit version> to 2.9.0 and there are now fewer exceptions (screenshot 2) but still no source files after I hit 'Set as Target Platform'

Any ideas?
