Xtext gradle plugin error [message #1764881]

I am a bit new to Xtext and gradle nevertheless was given an assignment by my manager to create headless build for our Xtext project. I am moving step by step and running mwe2 generator to generate the language infrastructure I have no issues. The Problem comes when running generateXtext which as I understand compiles Xtend sources. In the beginning I was getting Xtend compilation errors due o the fact that I was refering to java classes from different package of the same project. I read that this was a known bug and was fixed in latest Xtext reseases. So I upgraded to Xtext 2.12.0. This issue went away for now but I am faced with the different issue :

:generateXtext FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':generateXtext'.
> Could not resolve all dependencies for configuration ':detachedConfiguration2'.
> Could not find org.eclipse.xtend:org.eclipse.xtend.core:0752.
Searched in the following locations:
xxxxx://repo1.maven.org/maven2/org/eclipse/xtend/org.eclipse.xtend.core/0752/org.eclipse.xtend.core-0752.pom
xxxx://repo1.maven.org/maven2/org/eclipse/xtend/org.eclipse.xtend.core/0752/org.eclipse.xtend.core-0752.jar
xxxx://jcenter.bintray.com/org/eclipse/xtend/org.eclipse.xtend.core/0752/org.eclipse.xtend.core-0752.pom
xxxx://jcenter.bintray.com/org/eclipse/xtend/org.eclipse.xtend.core/0752/org.eclipse.xtend.core-0752.jar
Required by:
project :

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

I do not reference neither that version of the specified jar or even have no definition of detachedConfiguration2. What did I do wrong?

the question would be: which is the bad class on your cp and where does it come from.

setting the "xtext.version" property explicitely should help

e.g

subprojects {
ext.xtextVersion = '2.12.0'
}

Can you give some additional hints on what you do in the build
Do you consume Xtext p2 / eclipse artifacts?
