org.eclipse.xtext.ecore [message #1072282]

Hi,

where can I get the library org.eclipse.xtext.ecore from?

I want to add it as Maven dependency.

I found version 2.0.0 but this is not compatible (signing problems) with version 2.4.2 of Xtend lib.

I used this dependeny description:

<dependency>
<groupId>org.eclipse.xtext</groupId>
<artifactId>org.eclipse.xtext.ecore</artifactId>
<version>[0,)</version>
<optional>false</optional>
</dependency>

And it gave me version 2.0.0. But if I add the version 2.4.2 instead of [0,) then I get errors that it is not found.

Which repository has the correct version?

With regards,
Udo

Hmm,

I could find this here in the Maven repo:

<dependency>
  <groupId>org.eclipse.xtend</groupId>
  <artifactId>org.eclipse.xtend.standalone</artifactId>
  <version>2.4.2</version>
</dependency>

This includes almost everthing but not the package org.eclipse.xtext.ecore I mentioned above.

If I use this to load my DSL file:

public static void main(String[] args) {
  new org.eclipse.emf.mwe.utils.StandaloneSetup().setPlatformUri("../");
  Injector injector = new ConfigDslStandaloneSetup().createInjectorAndDoEMFRegistration();
  ...

I get the error

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/xtext/ecore/EcoreSupport
...
Caused by: java.lang.ClassNotFoundException: org.eclipse.xtext.ecore.EcoreSupport

Then I added the above mentioned lib and then I get the error

Exception in thread "main" com.google.inject.internal.util.$ComputationException: com.google.inject.internal.util.$ComputationException: java.lang.SecurityException: class "org.eclipse.xtext.resource.impl.DefaultResourceServiceProvider"'s signer information does not match signer information of other classes in the same package

...
Caused by: com.google.inject.internal.util.$ComputationException: java.lang.SecurityException: class "org.eclipse.xtext.resource.impl.DefaultResourceServiceProvider"'s signer information does not match signer information of other classes in the same package

and I suppose this comes from the wrong version number of org.eclipse.xtext.ecore.

How should I use the StandaloneSetup ?

Hi,

i dont think it is a good idea to missuse Xtext standalone. you may have a look at on

how to build a standlone thingy yourself.

Hi,

I looked at the link you gave me. After some time to learn the dependencies of the different pom and MANIFEST.MF files I got it running in my project with Xtext 2.4.2 (the example uses version 2.3.0 and in that version the dependent plug-ins are differently named).

I have following question:

How to mix different DSLs which are based on Xtext? Do I have to build for each DSL a standalone package?

I think it is very difficult to keep the versions of all dependent libs compatible all the time.

What is your strategy?

Hi I'd mix it all into one.
Or feed a maven repo with eclipse and Xtext plugins and use Tycho to
build the dsl plugins and manage maven deps on my own

I thought about the problem and I'd repackage all Xtext dependencies in 1 standalone jar. Then for each DSL I would package it itself as Maven dep.

That gives me the question: Would it be possible to package the Xtext deps as standalone from the Xtext project team themselves?

Everybody who uses Xtext DSLs in a Maven environment has to repackage it himself but it would be great if everybody could just add the dep from Maven central (or Fornax) to her project and just build the own DSL as Maven dep only.

Is this a feature request?
