Unresolved reference with dsl in jar library [message #1832404]

Hello,

I am trying to put default types of my dsl in a separate plugin.
My dsl is based on theTerminal grammar and does not used xbase.

I created a "Default" plugin with defaults.myDsl which contains all basics types I need.

My others project have a dependency in their Manifest on "Default" plugin.

I can reference types from "Default" without any pb when the "Default" plugin is opened in the current workspace.

Now I would like to put "Default" in a jar library. I exported the plugin to a fragment and installed it in my eclipse. In the plugin dependency of my projects, the "Default" plugin is found and contains the file defaults.myDsl.
My problem is that references are not resolved, it seems that "Default" plugin is not visible by xtext.

Do you have any idea how to resolve this pb ?

Thanks

Yannick

did you put your stuff to the classpath of the project that fails to resolve the references

The clasppath contains

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
	<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
	<classpathentry kind="src" path="src"/>
	<classpathentry kind="output" path="bin"/>
</classpath>

I think that the org.eclipse.pde.core.requiredPlugin should resolve the plugin location.

In the Plug-in dependencies of the project, the "Default" plugin is present and contains defaults.myDsl.

how does the requiredPlugins container in package explorer look like?
does it contain the mydsl file? can you share a screenshot?

Sorry, I can't share screenshot.

In the case the Default plugin is opened in the current workspace, the StateBasedContainerManager#getVisibleContainers returns list of handles [Default,Test]

In the case the Default plugin is a jar plugin I have only [Test]. I continue my investigation with the debugger.

In the case the Default plugin is not resolved, it's because the project is not accessible:
XtextProjectHelper#hasNature
--> project.isAccessible() --> returns false

so the Default project is closed.

This project contains only a myDsl file.

Yes it looks the same.

I don't know why the project is closed.

Thanks for your help. I continue to investigate.

The problem is resolved !

There was an error in my ui Module. I was using the SimpleResourceSetProvider instead of the XtextResourceSetProvider (by default).
