anonymous error using maven plugin

[Salvatore Romeo]

I'm trying to use the xtend maven plugin. I cleaned everything, leaving only the src folder and the pom, deleting the xtend-gen files too. 

While executing 

mvn compile -X 

I always get this error:

[ERROR] Failed to execute goal org.eclipse.xtend:xtend-maven-plugin:2.5.0:compil

e (default) on project scratch: Error compiling xtend sources in 'P:\dev\test\sc

\src\main\java'. -> [Help 1]

and no other information about which class is causing the problem.

Using eclipse everything works very well.

Any suggestion?

Thanks

Hi,

from looking at the code I see there might be ways through the code that can cause this situations.

Could you provide a minimal reproducing example and attach it to a bugzilla?

We will look into it.

Thank you!

Sven

I found the source of the problem was an active annotation: it didn't work on a class. 

Removing the class made the build work again.

Thanks you anyway
