Error in 15 Minute Tutorial Extended? [message #1819131]

Hello,

I am currently learning xtext and try to apply the steps outlined in the 15 minute tutorial Extended to write a code generator in xtend (which I also do not know yet).

For this I created a small grammar and generated all language artifacts.

My problem is a simple one:

The extended tutorial states that an xtend class has been generated which is to be used for further implementation. But this isn't the case. In the generated IDE plugin I found a generator skeleton but it is in Java not in xtend. The interesting fact is that this java class has been generated into the xtend-gen directory which hints at the fact that an xtend class should have been the result.

Is there some specific configuration needed to change this? Am I missing something?

I am using XText version 2.20.0.v20191202-1256 in the Eclipse DSL Tools version 2019-09 R (4.13.0)

thanks in advance

Lars

hi, i have no idea but the error you describe makes no sense to me-

this makes no sense. can you share your sample code e.g. on github?

Hi, thanks for your very quick reply.

actually I've just written a small grammar which I think shouldn't be necessary to be put on github.....so I've attached a screenshot.

There you can see you can see that in the project com.siemens.simgen in folder xtend-gen there is a file SimGenGenerator.java. If I understand the 15 Minute Extended Tutorial correctly it should be SimGenGenerator.xtend.

It says:
"First of all, locate the file DomainmodelGenerator.xtend in the package org.example.domainmodel.generator. This Xtend class is used to generate code for your models in the standalone scenario and in the interactive Eclipse environment."

(names need to be replaced....)
