TGG language: MWE2 workflow broken in latest stable release of MWE2/Xtext

[maxkratz]

Currently, the TGG language's MWE2 file (https://github.com/eMoflon/emoflon-ibex-ui/blob/master/org.emoflon.ibex.tgg.editor/src/org/moflon/tgg/mosl/GenerateTGG.mwe2) is broken for the latest version of MWE2 (v2.13.0) which is per default installed in our emoflon-eclipse-build (https://github.com/eMoflon/emoflon-eclipse-build/releases/tag/v1.0.0.202205241657-r2).

IIRC, the component Generator was marked as deprecated beforehand.

[maxkratz]

GT + Integrate are fine, AFAIK.

[maxkratz]

I noticed that the problem might not be MWE2 but Xtext itself. Release notes from the latest version (v2.27.0, https://www.eclipse.org/Xtext/releasenotes.html):

The org.eclipse.xtext.sdk does no longer package the deprecated org.eclipse.xtext.generator bundle. Please migrate to the new workflow/generator. The old and deprecated generator can still be found in the new org.eclipse.xtext.generator feature.

[maxkratz]

Yep, installing org.eclipse.xtext.generator.feature.group (e.g., here eMoflon/emoflon-ibex-eclipse-build@a837c0c) resolved the compilation issue (at least for now)

Nevertheless, the TGG language should be migrated to the new generator mechanism. (I will keep this issue open for that.)

@adrianmoeller This issue is resolved in the latest version of GenerateTGG.mwe2 (https://github.com/eMoflon/emoflon-ibex-ui/blob/master/org.emoflon.ibex.tgg.editor/src/org/emoflon/ibex/tgg/editor/GenerateTGG.mwe2), isn't it?
