I recently upgraded my Jenkins from 1.543 to Jenkins 2 and build-name-setter plugin automatically got upgraded from 1.3 to 1.6.5. However the build fails, here are the logs:

16:52:02 Set build name.
16:52:02 New build name is '#553'
16:52:02 Variable with name 'BUILD_DISPLAY_NAME' already exists, current value: '#553', new value: '#553'

OS: Windows Server 2008 R2 Ent./64 bit
Jenkins - 2.0 - Only Master no Slave
Java - 7 (7_49)
build-name-setter-plugin version: 1.6.5
Installed Jenkins directly using installer
tried multiple browsers Chrome, Firefox

I reverted the plugin to old version 1.3 and it works well with Jenkins 2.0.
