Finding Common Ancestor in a merge hook

talg1978

Hello,

I'm writing a merge hook plugin, and I need to find the common ancestor of two commits (in order to enforce a certain workflow based on this information).

I'm kind of new to Java, but I understand now that commitService is an interface and the getCommonAncestor method is not implemented there.

• Is there a concrete class implementing it?
• Is there another way to get the common ancestor?
• Maybe using the git api ? This might be even better, because I will need some more info from git down the road...

Thanks, Tal
