Christian, I looked a bit deeper in that part of the code and the EclipseOutputConfigurationProvider extends the IOutputConfigurationProvider.Delegate class which provides a default implementation of "getOutputConfigurations" (simply delegating it to its delegate in fact).
The EclipseOutputConfigurationProvider doesn't override this method but it simply provides an additional public method: getOutputConfigurations(IProject project). This method internally calls the super.getOutputConfigurations() which result calling the delegate.
This means that if I only provide my own IOutputConfigurationProvider which overrides the default path, this should work fine (as far as I understood) and the Eclipse integration will also be supported.
I debugged this and indeed, a EclipseOutputConfigurationProvider is still created and my CustomOutputConfigurationProvider is correctly injected as the delegate (via the injected EclipseOutputConfigurationProvider constructor).
Now, I think I understood my problem: if you look at the BuilderPreferenceAccess class, you can see that it expects an OutputConfigurationProvider to be injected (in the setOutputConfigurationProvider method). Shouldn't that be a IOutputConfigurationProvider instead ? That's why the default Xtext OutputConfigurationProvider class gets injected instead of my own CustomOutputConfigurationProvider.
I made a litle test: I made my CustomOutputConfigurationProvider extends OutputConfigurationProvider (instead of implementing IOutputConfigurationProvider) and I provided two bindings in my ui module:
public Class<? extends IOutputConfigurationProvider> bindIOutputConfigurationProvider() {
return CustomOutputConfigurationProvider.class;
}
public Class<? extends OutputConfigurationProvider> bindOutputConfigurationProvider() {
return CustomOutputConfigurationProvider.class;
}
If I run that code, my problem is fixed and the default output path is not "./src-gen" in the property page anymore.
Is this a bug or desired behaviour ?
