NoClassDefFoundError when using the system area

I am currently encountering and exiting when using Maven with NetBeans 7.1. I have included a library that I cannot host in the Maven repository in the System area. It looks something like this:

 <dependency>
    <groupId>org.company</groupId>
    <artifactId>FBTM</artifactId>
    <version>1.0-SNAPSHOT</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/FBTM-1.0-SNAPSHOT.jar</systemPath>
</dependency>

It seems that the IDE has picked up this dependency, as shown in the Dependencies folder (Project View), and I can view the contents of the jar. I can also import classes from the can without any problems.

However, when I try to start my project (and the runtime has any of the classes used), I get NoClassDefFoundErrorfor the class in question. It can be any class.

Stacktrace:

Exception in thread "main" java.lang.NoClassDefFoundError: com/company/otaupdate/sim/commands/Select at com.company.fbtranslationlibrary.mc.scripts.UserData$1.<init>(UserData.java:30) at com.company.fbtranslationlibrary.mc.scripts.UserData.<init>(UserData.java:28) at com.company.fbtranslationlibrary.mc.MS.get_profile_script(MuscadeScript.java:80) at com.company.fbtranslationlibrary.mc.MS.access$300(MS.java:16)

Any help or pointers would be greatly appreciated!
