Problems with complied GT1.2

[Yexeed]

I have some troubles when attempt to launch the compiled GT1.2 sources. I'm compile it using mvn clean and mvn package, taking jar from target folder and writing java -jar nukkit.jar but getting unexpected closing:

root@deb:/kekerbob/target# java -jar nukkit*
Using log level 'INFO'
root@deb:/kekerbob/target# java -jar nukkit*

Seems that you forgot language files.

and how to fix it?

Build JAR file

git submodule update --init
mvn clean
mvn package
