I just refactored my meta-model by splitting it into two separate ecore files, one for application-specific components and one for platform-specific components.
I loaded the resources from the application-specific meta-model into the platform-specific meta-model, created a single genmodel that contains both meta-models, and successfully generated the model editor plugin and started the new Eclipse. In my existing mtl file templates, I added the module imports to the top line of the mtl files to successfully wire the new dependencies.
However, one last problem remains that is stumping me. I recreated a new clean main.mtl and Main.java files.
Inside Main.java, there is a method called registerPackages. In the method, there are a bunch of calls to: resourceSet.getPackageRegistry().put(packagepath...)
They are all unresolved. Is there something obvious I'm missing?
Thanks for any help!

Hi Jeff,
I'd say you're missing the required dependencies for these packages to
be resolved. If these packages are necessary (and I believe they are),
you'll have to open the META-INF/MANIFEST.MF file of your plugin and, on
the "dependencies" tab (at the bottom of the editor), you'll have to
"Add" dependencies towards the required plugins.

Hi Jeff,
If the "bin" folder of one of your projects doesn't contain the "class"
files corresponding to your "java" sources, the most probable cause is
that you have disabled the automatic build of your Eclipse. "Project" >
"Automatic Build" must be ticked.

Hi Jeff,
I must admit I'm quite confused right now.
Could you briefly describe which projects you have in which Eclipse
workspace? If you followed one of the EMF tutorials I can think of when
defining your metamodel (the project that contains your genmodel), you
should have something resembling this :
"main" Eclipse, the first you launch :
com.xyz
|- src
| |- com
| |- xyz
| |- XYZPackage
| |- ...
|- model
|- xyz.ecore
|- xyz.genmodel
com.xyz.edit
|- ...
com.xyz.editor
|- ...
Then, in the "runtime" Eclipse, the one you launch from the "main", you
should have all of the projects that depend on the "xyz" model,
including your Acceleo project.
You shouldn't have _twice_ your metamodel project (containing your
"XYZPackage"), it should only exist in the "main" Eclipse workspace.
