Before I say anything, I just want to say that I have the same problem @john96dk had, but his was marked invalid.
I Checked everything I could think of, including the stuff in CONTRIBUTING.md, and found no issues that may be causing this. I tried the normal version and the rewrite version. Here are the errors:

I would add a dropdown thing but I cant find it.

I am running git-Spigot-e000104-4cb3258 (MC: 1.9.2) on my server. A full log of it can be found at http://pastebin.com/TbfMRdfq

Update Java, I guess Steffion built it on Java 8, I guess the "51" thing is related for Java 7. Please correct me if I'm wrong^^

Steffion commented

Make sure you are running Java 8 first, if so I will continue having a look at it.
