After Migration 2.10 -> 2.11. Cannot start application [message #1753810]

Hello All

I've moved my application from Xtext 2.10 to XText 2.11 platform.
When I rebuild application I observed the following error

-----
Errors occurred during the build.
Errors running builder 'Xtext Project Builder' on project 'com.psl.atom'.
org.eclipse.xtend2.lib.StringConcatenation.append(Ljava/lang/String;)V
----

I don't use xtend language in my code
I use Eclipse (Mars + xtext 2.11) (32-bits)

I cannot understand what is the reason of this bug.

Thank you in advance
Alex

it looks like you still have somewhere a 2.10er version of xbase.lib floating around.
StringConcatenation for new methods in 2.11 and these will be used

I had a similar error. Updating the Xtend version fixed it for me.

I've checked version of installed plugins via (Help->Installation details).
Look at attached screenshot

All version of plugins from XTEXT framework is 2.11

UUPPS : I found the reason in Run Configuration in plugin section there were two libraries 2.10 and 2.11. I've checked out old library. Problem is fixed

I observed the interesting behavior. I observed this issue again. I check run configuration, the old library (2.10) was unchecked, Take into consolidation the following scenario
- So I've checked in old library run build
- Observed error again
- I've checked out the old library run build
- The issue is not observed

Seems to me old library is there in class path somewhere
