Hi George, I am now working on the testing addon <https://issues.jboss.org/browse/FORGE-2545>;. I started my work on it a couple of weeks ago, developing against Forge 2. But after Forge 3 was moved to master, I changed my addon accordingly. Unfortunately, now after I build and install it, it doesn't work anymore. I mean, the command testing-setup is not available neither in the IDE, nor in the shell. Most probably I am missing some dependencies, I don't know. But it was working fine while built against Forge 2. Here is the Forge Core code together with my addon: https://github.com/ivannov/core/tree/FORGE-2545 The addon itself is here: https://github.com/ivannov/core/tree/FORGE-2545/testing i will be very happy if you point me to what I am doing wrong :) Thanks, Ivan
