[Xtext] Need help with implicit imports [message #1398635]

I am trying to get implicit imports working in my project [0]. The models [1] to be implicitly imported are wrapped in a plugin project [2]. The DSL plugins have a dependency on the plugin project (aka library project).

I have implemented the custom ImportedNamespaceAwareLocalScopeProvide [3]. Also, configured the same in the runtime module [4].

When I deploy/launch all my plugins (dsl + library), I assume the models (from the library) should show up in the content assist. However, that doesn't seem to happen.

Can someone please take a look at my code. Perhaps I might be doing something wrong. I went through a couple of threads related to implicit imports, however I have had no luck so far. Would be great if someone could help.

you need a dependency from the project containing the .yourdsl files to the libary project.
it does not help to put the dependency to the .dsl or .dsl.ui project

i am not sure what to do if you want to have the dependency to the libary project implicit as well.

Hi,

there are ways to achieve the desired behavior. What you could try to do
is to use a the bundle reference to the lib and resolve known classpath
URIs against that bundle. The resolved instances can be made available
in your scope provider and in your content assist implementation. In
general it is a better idea to make the library available on the user
side by means of explicit project dependencies as Christian already
pointed out.

Regards,
Sebastian
