Xtext Classpath-Based global scoping [message #898961]

In the Xtext Documentation I found the following:

"By default Xtext leverages the classpath mechanism since it is well designed and already understood by most of our users. The available tooling provided by JDT and PDE to configure the classpath adds even more value. However, it is just a default: You can reuse the infrastructure without using Java and independent from the JDT."

When I configure classpath-based global scoping as described in the help, the scoping works only if my project is Java Project (has Java Nature and Java Builder).
In other case, it doesn't work.

The questions is how I can reuse the infrastructure (classpath-based global scoping) without using Java and JDT?

Hello Sandra,
I am not sure what your intention is. You can not use class paths without java, because the class path is only defined in java and plugin projects. You can use project dependencies in your workspace and references to other model files by changing the container state in your <DSL>UiModule like
public Provider<IAllContainersState> provideIAllContainersState() {
return Access.getWorkspaceProjectsState();
}

If this is not, what you meant, you can explain perhaps.

Regards,
Benjamin

If you want to look at a project that is using Eclipse Projects and that
sets up depedencies between projects based on meta data in the projects,
you can look at cloudsmith / geppetto @ github. No JDT functionality is
used in Geppetto.
Note that if you package a product that does not include jdt, there are
a couple of other things to also deal with regarding aggregatin of error
markers in the project/package/navigator views. (See the "jdt-ersatz"
stuff in geppetto what is needed).
