Detecting craftbukkit build within plugin enable.

It seems that every day I get a couple posts saying 'plugin does not work', only to find the person is using a version of craftbukkit lower than the specified required build number.

I was wondering if there is a way to check what build a person is using when the plugin is enables, so I can print out an appropriate message? If not, there should be~ :3

Thanks to anyone who can help!

Edit:
Someone messaged me about this.getServer().getVersion(), but the build number isn't in this string since build 327!

 

Code:

CraftServer.class.getPackage().getImplementationVersion()

That will get you something like this "git-Bukkit-0.0.0-398-ge2ce3db-b311"

 

This returns the same as this.getServer().getVersion() but minus the " (MC: " + protocolVersion + ")"

In the more recent builds, it will only return something like git-Bukkit-"39a3bf4", which doesn't help me. Also versions older than build 231 don't include a build number. (Perhaps someone forgot to add the build number to the string during the recent bamboo migration?)

Edit:
Or perhaps there is some way to lookup the "39a3bf4" into a build version?
In any case, I think the build version needs to be re-added asap, so such a lookup table doesn't have to be long.
