This package is generated by the Xtext generator. You've to run the MWE2 workflow to get the corresponding code.

From what I know from https://github.com/Nodeclipse/coffeescript-eclipse
is that Maven has no way to call Xtext and @pulse00 Robert committed Xtext generated code.

Possibly @cdietrich or @michael-schnell (https://github.com/fuinorg/emt-xtext-archetype) know better

[cdietrich]

what do you mean by "call xtext"

[paulvi]

"call xtext" to generate files, or in other words how to build Xtext project with maven/tycho (without IDE)

[paulvi]

OK, example of using Xtend within tycho build is jeeeyul/eclipse-themes#154 by @jvanzyl

[cdietrich]

there are several possibilities.
https://github.com/cdietrich/xtext-maven-example
https://github.com/svenefftinge/maven-xtext-example
in my current closed source project with build not with tycho but with apache felix bnd plugin

[michael-schnell]

Actually there is an Xtext Maven plugin you can use to generate the code:
http://kthoms.wordpress.com/2011/12/08/xtext-2-2-finally-brings-maven-support-for-xtend/
Of course it requires to use Maven Tycho for the build.

I haven't tried it out yet - I simply added the generated Java source code to the GIT repo (Poor man's solution, until I find the time to use the plugin).

[paulvi]

@michael-schnell It does not matter how the solution was created, but whether it solves and is kept updated.
