The full error there was:

[ERROR] Error building bundle org.isatools.plugins:isavalidatorconvert:bund=
le:1.0 : Exception: Not a valid class file (no CAFEBABE header)
[ERROR] Error building bundle org.isatools.plugins:isavalidatorconvert:bund=
le:1.0 : Invalid class file: *.class

For some reason, not everything copied. This is what you get when working l=
ate :)

The maven-bundle-plugin will take care of most of the stuff you're trying t=
o do in your maven-assembly-plugin and is a cleaner approach. This will als=
o ensure that you don't get erroneous dependant .jar files compiled in with=
 your application.
