Solved Building Craftbukkit with Maven

Hey,

i'm having throuble building Craftbukkit with Maven.
I got the Repo cloned and wanted to build it.
It works fine to the Maven-Shade plugin.

There I get the error:

Code:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:1.4:shade (default) on project craftbukkit: Error creating shaded jar: Unknown local variable 6 -> [Help 1]

Stacktrace from Maven Shade Plugin:

Code:java

Does anyone know this problem and know any sollution?
Thanks in advance.

Okay. Seemed to be a Maven issue.

Cleaning the .m2 folder did the magic (redownload of 2 gb though... -_-).

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Another solution is to change CraftBukkit's POM to use maven-shade-plugin Version 1.5 or better (most current version is 2.2).

 

This really solved the Isue! Holy sh....

You really saved my life and my time!
