Problem when build test with Eclipse/Maven/TestNG, NoClassDefFoundError

So I've tried and I've tried for a week now but I can't get it to work. I'm sorry. I've red many FAQs here on launchpad, but I really cant get it to work. Heres is my problem:
I have a Maven project in Eclipse with TestNG and Sikuli. When I run the test as Run as -> TestNG Test it works just fine. But when i run the test as Run as -> Maven test, I get this error: java.lang.NoClassDefFoundError: org/sikuli/script/FindFailed

Here is some info regarding config etc etc:

Sikuli version = SikuliX Setup Build: 1.0.1

And here is how my Java environment looks like:
Java version:
C:\Sikuli X>java -version
java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) Client VM (build 24.55-b03, mixed mode, sharing)

Java installed under:
C:\Program Files (x86)\Java\jdk1.7.0_55

Path looks like this:
C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft\Web Platform Installer\;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Sikuli X\Sikuli-IDE\libs;%JAVA_HOME%\bin;
