I’m trying out the SDK for the first time and I’m having trouble debugging a module in Eclipse. I’m using Ignition 7.8 and Maven. I took the 7.8 example modules from github and I was able to run and modify a couple of the modules without any problems. However, when I tried following the instructions from the old SDK programming guide (I didn’t see a new one) for debugging in the designer, I got this error: “Error: Could not find or load main class=127.0.0.1:8088:8043.main.” I checked the gateway and SSL port and they match. I’ve never used Eclipse before and I’m not even sure where the “-Djavaws.sr.gateway.addr.0” comes from so I’ve been stuck here for a couple hours. Any suggestions would be really appreciated. Thanks in advance. ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/4/446ea0ba110641b2ca5bbbb35d06bbe3c78ea43f.PNG) ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/5/55a0fc1b1196ce41f29065f167545364717b6fd3.PNG) ---

Okay, it’s working now. Travis pointed out that I had some spaces in the command line.
