Hi,

When creating an xtext project from existing an ecore model I get an error when generating the xtext artifacts. The genmodel isn't mapped.

The project is created usign xtext 2.13 and I select to create a language server:
- no Eclipse plugin, only Generic IDE Support
- Preferred build system: Gradle
- Build Language Server: Fat Jar
- Source Layout: Maven/Gradle

(I'm trying to follow this http://typefox.io/building-a-vs-code-extension-with-xtext-and-the-language-server-protocol which works if I start from a grammar)

The output I get in the console is as follows:
0    [main] INFO  text.xtext.generator.XtextGenerator  - Initializing Xtext generator

did you add a gradle dependency to the defining plugin?
does the jar file include the genmodel files and if yes in which location?

I just ran the wizard and then tried to create the xtext artifacts. How do I do that? I'm quite new to Gradle, sorry.

Not sure which jar file you are referring to.

It is in 'model/MyDSL.genmodel' in my.dsl.model.jar

If you by mydsl mean the project containing the genmodel, then no. I haven't changed any gradle files as I'm a gradle illiterate. I exported the jar manually.

I assume that the 'genmodel project' needs to be build with gradle and then that it is referenced somehow from the 'xtext projects' gradle files?

My naive assumption was that the xtext wizard would set this up.

no it does not. it does not know where these other project come from, if they are in the same ractor etc
i recommend you to either move the metamodel project to the mydsl.parent, adapt settings.gradle, and add a project(":xxxxx") dependency to build.gradle
or to provide it by a second maven/gradle build and then reference it as jar, and use/add a repo to the configuration.
=> you need to have some basic gradle knowledge.
