So i am running the latest version of world edit,and everytime i want to //set block , bukkit throws NoClassDefFound errors.Any clue how to fix it?100% are not conflicts between plugins i personally tested that.
What's your Craftbukkit version? It's very possible that the version of world edit you're using is colliding with the Craftbukkit you use.
Use the latest development WorldEdit jar: http://build.sk89q.com/job/WorldEdit/ As fatmanjumprope said, you are probably running a recent craftbukkit version with an old / incompatible worldedit jar.
I am using build 2541 or something.I just took a newer version for lockette to work. I took the last version of World EDit! I said that i use the latest v of world edit ....any other idea for it? EDIT by Moderator: merged posts, please use the edit button instead of double posting.
Please provide a link to your full startup log so we can verify your versions. In my experience, "Latest version" tends to mean "latest version that I was able to find" or "latest version, aside from the version that I didn't know was released". The startup log isn't susceptible to those types of unavoidable human fallacies.
You're running a post-R0.2 development build of CraftBukkit, which causes many plugins to break. You'll either need to downgrade CraftBukkit to the latest Beta build or upgrade your plugins to their latest development versions, if available and if they've been made to work with the recent builds. See this for more information.
It's your server, you do what you want. Personally though, I like to manage that sort of thing on my own, manually. I find there's less of a chance of something breaking, and more of a chance that I'll know how to fix it when it does break, if I do it myself.
