Hello,

I would like that my dsl files which are not on the java classpath to be ignored by the xtext builder for generation/validation.

I tried to use the StrictJavaProjectsState with Domainmodel example.
I added in DomainmodelUiModule
	  @Override
	  public Provider<IAllContainersState> provideIAllContainersState()
	  {
	    return Access.getStrictJavaProjectsState();
	  }


Then I created a java project with a test.dmodel in the src folder.
Its content is correctly generated in src-gen folder as expected.

Then I moved test.dmodel in a folder outside the java classpath. I was expecting that the file will be ignored but it is not the case, its content is generated in src-gen folder.

How can I prevent this behaviour ?

Regards,

Yannick

Ok thanks

I think that https://github.com/eclipse/xtext-xtend/blob/master/org.eclipse.xtend.ide/src/org/eclipse/xtend/ide/XtendResourceUiServiceProvider.java
will do the job.
