missing groovy-all jar

I am trying to download the latest /groovy/groovy-all/1.8.0/groovy-all-1.8.0.jar from Eviware repository (via Nexus Professional 2).

I can see the file is available on the remote site:

http://smartbearsoftware.com/repository/maven2/groovy/groovy-all/1.8.0/groovy-all-1.8.0.jar

However, after configuring the Eviware repository via Nexus, I cannot see this jar version in the index nor download.

So, only the pom appears to be available , unlike for previous versions (e.g. 1.7.4) where the jar is evident.

Any suggestions appreciated.
