Reference to files from plugins or projects [message #1750170]

Hello together,

i wrote a grammar to reference EObjects from other .ecore-Files. This works fine if i copy the file directly besides the .mydsl-file.

eobject=[ecore::EClass|FQN]

What i want is to reference to eobjects from .ecore-files from other projects or plugins. How can i achieve this?

Thank you for your time.

Greetings,
Simon

Simply put it on the classpath e.g. By turning your model project to a plugin project and add the library plugins to the dependencies in manifest

Hello Christian, thx for the advice.

Sadly it doesent work. I converted the project that contains my dsl-file to a plugin project and added another plugin that conaints an .ecore-file to the plugin dependencys. no difference

Does that other project have xtext Nature?
Can you share a complete reproducible example

As always your Questions are right on point. With the added XText-Nature it works with a project thats in my workspace.

however i need to use an .ecore-file thats packed in an eclipse-plugin. how can i add xtext nature to a plugin? Or is there another way?

Then you don't need. Simply add the dependency (and make sure it is really packaged (build.properties)

i can see the plugin that contains my .ecore-model under Plug-in Dependencies Entry and within the .ecore file. So i guess its packaged. (Selected under binary build, in Source build its unchecked). is that correct?

that looks legit,
if you have a look at the plugin in the "plugin dependencies" in the package explorer of the test.mydsl containing plugin project,
is the ecore file visible?

One more Question: Why are the objects i get from the resource like this: platform:/resource/<project>/<path> and not platform:/plugin/<project>/<path> ? I get errors if i try to save it

from the Elements i get from the getScope-method.

i try to save the emf-model i get from the mydsl-editor into another emf-instance-model. and i always get the error Resource '/<project-name>' does not exist. Wich is true because the resource is a plugin and not a project that i have in my workspace.
