2) I've started this Eclipse and created a new XText project
3) I copied my old EBNF and make some changes for compatibility with
TMF-XText-0.7.1
4) run the workflow GenerateDsl.mwe
And now the problem, the parser was not generated.
" org.example.dsl.contentassist.antlr.internal.InternalDslPars er cannot
be resolved to a type".
In the project "dsl.ui" exists a package
"org.example.dsl.contentassist.antlr.internal". May the needed parser
should generated in there.
In documentation I found the hint to download separate ANTLR feature,
but it is installed yet.
