Hello

I observed strange problem. In new version of Xtext 2.9.

--- I've created simple hello world project. Using maven as build system and using standard maven file layouts
--- try to generate xtext artifacts, For this I click corresponded options in menu that displayed for MyDsl.xtext file.

Then I observed message like Please put bundle org.eclipse.emf.mwe2.launch on project's classpath




Wthat is the reason of this problem

Hi,

i cannot reproduce that

- using xtext 2.9.1

did you try to clean your local maven repo, and then recreate and run the workflow

Hi

I think this is entirely normal. I'm sure I've seen it with Xtext < 2.9
(I still have to use 2.8.4) and non-Maven usage.

org.eclipse.emf.mwe2.launch is needed if you have the default
configuration in which the MWE2 build script is launched for the same
project as the generated Xtext Java files. It's more effort, but I
recommend separating all the build support into a separate plugin and
avoid the unnecessary dependencies/run-time bloat.

Regards

Ed Willink

I've update my instance of eclipse to 2.9.1 version. Problem is observed on updated version. I tried to build project using maven command (I ran mvn clean package command.) line and caught the following exception
0    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] INFO  text.xtext.generator.XtextGenerator  - Initializing Xtext generator
191  [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] ERROR mf.mwe2.launch.runtime.Mwe2Launcher  - org/eclipse/emf/codegen/jet/JETException
java.lang.NoClassDefFoundError: org/eclipse/emf/codegen/jet/JETException

The full stacktrace in attachement.

Thanks
Alexander

which opptions did you choose in the dialog?
this exception is in org.eclipse.emf:org.eclipse.emf.codegen
can you share a project that reproduces the problem?

p.s.

this error happens if you execute a maven only project (no tycho)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=485129
the bug will be fixed in 2.9.2+

as a workaround you may use
