Update URL to bukkit Maven Repo

I was trying to build with Maven and got this error:

[ERROR] Failed to execute goal on project GroovyBukkit: Could not resolve dependencies for project org.bukkit.plugin:GroovyBukkit:jar:0.8-SNAPSHOT: Failed to collect dependencies for [org.bukkit:bukkit:jar:1.2.4-R1.1-SNAPSHOT (compile), org.bukkit:craftbukkit:jar:1.2.4-R1.1-SNAPSHOT (compile), org.codehaus.groovy:groovy:jar:1.8.6 (compile), junit:junit:jar:4.10 (test)]: Failed to read artifact descriptor for org.bukkit:bukkit:jar:1.2.4-R1.1-SNAPSHOT: Could not transfer artifact org.bukkit:bukkit:pom:1.2.4-R1.1-SNAPSHOT from/to bukkut-repo (http://artifacts.lukegb.com/artifactory/repo): artifacts.lukegb.com: Unknown host artifacts.lukegb.com -> [Help 1]


Changing the repo URL fixed it.
