Importing external classes

[Curt Albert]

I am wanting to import a package from external project into one of my
substitutions in com.oracle.graal.replacements .  I was using Netbeans to
compile it and I added the library in Netbeans so it will compile correctly
but when I try and run mx vm I get the error:

[thread:1] scope:
  [thread:1] scope: RegisterReplacements
    [thread:1] scope: RegisterReplacements.InterceptException
    Exception occurred in scope: RegisterReplacements.InterceptException

Also when I try to build with mx build I get the error that the package I
am trying to import does not exist.

How can I add the external package so that mx can find it?

Thanks,
