Error creating Xtext artefacts [message #1797003]

Hello,

I made the following DSL (attached file) with Xtext. My problem is the error message. This message names a couple of unreachable options concerning the definitions of datatypes. I need all of them.

I've read a lot here in the forum. But I couldn't find the right solution.

Cheers

Please read the advice in this blog post:

In general, you are trying to do too much by terminal rules and should use datatype parser rules to avoid ambiguity of terminal symbols.

Hello Karsten,

Thanks for your reply!

I tried to solve the problems with datarules. But I had the same problem.

Do you have an advice, which part I can cover with datarules?

Cheers

You can combine tokens to datatype rules. See QualifiedName rule from Xtype.xtext for example.
