I noticed when I was doing some testing that if you specify the blue ocean plugin, version 1.8, the library won't be able to find the url since it is 1.8.0.
Closing this since tool should throw error if users enter the wrong version. After some discussion, it seemed like the case where there's a mismatch between the version of the dependency listed and the actual plugin probably shouldn't happen that often and is probably an error with the plugin that listed the dependencies that should be addressed.
