Invalid openmrs-test-1.6.6.jar posted to maven repository

I just tried building the latest version of the metadatasharing module which has a dependency on the openmrs-test-1.6.6.jar file, and building fails to to an error opening this file:

[ERROR] error: error reading /home/mseaton/.m2/repository/org/openmrs/test/openmrs-test/1.6.6/openmrs-test-1.6.6.jar; error in opening zip file

To confirm that this is indeed a problem on Nexus and not just in my local .m2 directory, I went directly to this link:

http://mavenrepo.openmrs.org/nexus/content/repositories/public/org/openmrs/test/openmrs-test/1.6.6/openmrs-test-1.6.6.jar

And after downloading this file onto my Desktop, I am unable to open it as well.
