Hi,
I have a Xtext project with two xtext files having cross reference. When I tested the project as an Eclipse plugin, it worked well. Now I'm trying to create a shadowJar using gradle in order to implement my DSL in Eclipse-Che. The project generates artifacts without errors in the Eclipse editor. However, when I tried to build the shadowJar in the command prompt, I get an error saying 'XtextLinkingDiagnostic: null:1 Couldn't resolve reference to Grammar 'org.xtext.projection.CustomTerminals'.'
I will post my 2 grammar files, mwe2 file and the full error message below: -
Projection.xtext: -

Could anyone please help me resolve this error?
