This might not answer your question as it isn't about Eclipse. It is relevant though as it deals with invocation:
On my system I have GEP and ECJ installed in different directories. GEP access ECJ through ECJ-18.jar.
A command line invocation looks like:
java -classpath ./;C:\Users\100436574\workspace\gep\ecj-18.jar;C:\Users\100436574\workspace\gep\ecj-gep18.jar;C:\Users\100436574\workspace\gep\javacsv.jar;C:\Users\100436574\workspace\gep\meditor.jar ec.Evolve -file ec/app/gep/Galaxies/Galaxies.params

Subject: linking GEP to ECJ
I got ecj working nicely, and gep compiled, both in Eclipse.
However, gep tests don't see ec.evolve in ecj.
