Language A accessing B language during code generation [message #1787591]

Hi guys,
I have two Eclipse xtext languages, project A and project B, each one with a grammar.
Language B is a code generation complement for language A.
Language A starts the code generation and it must call some methods in language B to help the work (I do Eclipse Extension Points to solve this). After, language B starts its code generation, based on elements defined in language A.

All works fine when the two plug-ins are executed in Eclipse IDE.

But it fails when running in continuous integration with Maven because Maven cannot access the extension points and so some files aren't generated as in Eclipse IDE.

Some hint about the right way for how language A can access language B during the code generation?

Some hint about how language A can access language B during the code generation without Eclipse extension points? Or there is another way to achieve this?

Thanks,
Márcio Koch.

can you be more explicit what you mean by "access"

Thanks for the quick reply.
The language A declares an interface (and an Eclipse extension point) that language B implements.

Language B knows A language by a referencedResource, but language A does not know B language.

if you use guice to hook up/register the services you could try something like

@Inject
		IGlobalServiceProvider gsp;
		
		public void doSomething() {
			gsp.findService(URI.createURI("dummy.b"), ServiceClazz.class)...
		}
