Standalone generator & models in multiple jars [message #1061937]

Hi,

I have two projects both containing files for a DSL I've designed. I'm using maven and have declared the dependency as required. The base project packages the DSL files inside the jar artifact that gets generated.

I get an error when invoking from maven and I try to load a DSL file that references elements that are in the jar file of the project dependency.

I'm using the code below:

Provider<XtextResourceSet> resourceSetProvider

.....

XtextResourceSet resourceSet = resourceSetProvider.get();
resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);

// Iterate through all the files in a configured directory and add to resource
URI uri = URI.createURI(file.getPath());
resourceSet.getResource(uri, true);

I thought that by setting OPTION_RESOLVE_ALL Xtext will index the classpath to find the DSL resources.

So, if I don't know the name of the jar files in advance, is there a way to tell Xtext to scan the classpath and find the DSL resources? Eclipse does it in a way as I'm able to navigate from a DSL file in one project to another project even with "workspace resolution" disabled.

Any help will be appreciated.

Thanks, Karel

Hi,

you have to scan for resources and load them to the resourceset yourself.
this is intended.

you may use org.eclipse.xtext.mwe.Reader
instead of doing the resource handling yourself
