Hi everyone,

I've created new Xtext project from my ecore model. After some problems I've generated correctly Xtext Artifacts. Now, as usual, I've launched an Eclipse instance and I've created a new project. But when I create a new file with my extension will not appear dialog for adding Xtext nature to the project.

Why is this happening?

I think there is still something wrong generated. As a first step I
would compare plugin.XML and plugin.xml-gen
Then I would have a look at the OSGi console and check if your
languages ui plugin is correctly started

PS make sure you use builderintegrationfragment in your workflow

How can't I see that? There isn't a generated plugin!

When I create the project no plugin.xml was create automatically, so I've written the plugin, but there isn't generated one.
Doesn't it like my plugin?


<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

<plugin>

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.rcpvision.it/ats/suitetest/CoreLanguage" 
       class = "it.rcpvision.ats.suitetest.corelanguage.LanguagePackage"
       genModel = "it/rcpvision/ats/suitetest/CoreLanguage.genmodel" /> 
	
 </extension>
</plugin>

Am talking about the ui project not the runtime project. What does
the console say?

Hi,

Is the editor generally working? Is the only missing the the
natureaddingcallback. Did you check the builderintegrationfragment as
I said?

Thanks for replies.

Yes, I've got 
fragment = builder.BuilderIntegrationFragment {}
in my .mwe2

The editor doesn't work: I see the file with the default editor, no editor for my language is avaible.

But now I've got following exception:

Hi there does not seem to be any hint on Xtext in that log. Please
use the OSGi console to check if the ui plugin of your lang is
started

And why doesn't it start.

I've tryed with library example and it works.
So, here what I've done from the begin:
1) I have an ecore model
2) I've created new Xtext project from my existing ecore
3) I've changed imports with right strings (see below)
4) Generated Xtext Artifact
5) Run Eclipse Application
6) Create new java project and new .myextension file

With library it works, with my ecore plugin doesn't start.

import "platform:/resource/com.egicon.ats.sequence.model/model/AtsVariable.ecore" 
import "http://www.eclipse.org/emf/2002/Ecore" as ecore
import "platform:/resource/com.egicon.ats.sequence.model/model/AtsTypeSystem.ecore" as typesystem
import "platform:/resource/com.egicon.ats.sequence.model/model/AtsSequenceEdit.ecore" as sequenceedit
import "platform:/resource/com.egicon.ats.devices.model/model/configuration.ecore" as configuration

Solved.

Problem was that some plugin in dependences uses Java 1.7.

Thanks for interesting.
