I've installed ros-indigo-ur-msgs and it's current version it 1.1.11.
Current version in the repo appears to be org.ros.rosjava_messages:ur_msgs:1.0.5 which is behind.
The rosjava message generator cannot be used to build a package which depends on ur_msgs due to the version mismatch (it tries to download the 1.1.11 version which is not available).
