Fortify com.fortify.dev.ant.SCAListener could not be loaded because of an invalid dependency

Question

Has anyone seen this issue before? I tried running fortify with verbose on but all I get is: Compiler execution failed (exit code: 1)

I am trying to run fortify source with an ant script.

EDIT:

sourceanalyzer -b name -source 1.5 ant -D(some var) target

I have no problem when I do:

sourceanalyzer -b name -clean
