How to update server to 1.9 prerelease?

How would I do this and would I have to generate a new world?

Because if we lose all our current structures I dont think I want to do it...

 

You CANNOT use bukkit with 1.9 prerelease and there WONT be a recommended build before 1.9 is officially out.

 

Ok thanks

 

1.9 Official WONT be comming out, Jens just tweeted that

 

Well, that's a bit misguiding. It will be released, it's just that we still don't have a release date.

 

From what I understand of that tweet (found here: http://twitter.com/#!/jeb_/status/123306381427220480) is that they'll continue doing pre-releases up to Minecon and then just do a full release.

 

No Wiliamsson, Porydan2 is correct. There will be NO 1.9, just the final Release. I know how to read.

 

There will be no formal 1.9 release: http://notch.tumblr.com/post/11309884313/pre-releases-and-adventure-updates

 

So the next time Ill be able to update my server is when Minecraft releases? 11/11/11

 

I think it might even be 18/11/11. You can still run the pre-beta builds directly from Mojang if you want to, but apparently they're quite buggy, and of course don't support any Bukkit plugins.

 

So can i update or not you people confuse me
Plz answere

 

Heh, here:

1. Backup your whole server folder just in case.
2. get the 1.9pre5 CB .jar here: http://ci.bukkit.org/job/dev-CraftBukkit-1.9/
3. rename it or rewrite your start.bat to point at it.
4. get 1.9pre5 MC client.
5. hope all your plugins work. (only 1 of mine didnt, from the version string i assume)

 

@Rwembee
You do know that CraftBukkit for 1.9 is unstable and is just a development build!?

 

I have 1.9 official it came out yesterday
