I’ve been trying to deploy our newly written java code to our competition robot, and i’m getting this output when running:

It couldn’t find your roborio. We’ll need more information about your setup. The following questions follows my standard troubleshooting process (both as a CSA and in my everyday life), so hopefully it’ll help you find the problem and you won’t have to run down the whole list.
Is the Rio powered on?
Are you connected through Ethernet? USB?
Is the cable plugged in on both sides?
If Ethernet, are you connected through the robot radio, or direct to the Rio?
Do you have a static IP address set, or DHCP?
What IS the IP you have on the laptop?
Does anything else see the rio? (DS app on the same PC? DS on another PC?

Something I noticed was:
Up-to-date check for task ':discoverRoborio' took 0.0 secs. It is not up-to-date because:
Task has not declared any outputs.
That looks like the most likely indicator of the problem.
Unforchently I havn’t encountered it befor and am not an expert on the integral workings of gradle. In the meantime I’ll let you know if I stumble across a solution.
It’s errors like these that keep the programers up at night. Let the grimlin chasing begin.
If you find the problem I would apreate if you let me konw in the case my team runs across it in the fucher.
We were previously running a LabVIEW startup app from worlds. We had a lot of problems deploying code because the roboRIO CPU usage was hitting 100% due to many parallel control loops running very quick in our code. I assume this was taking so much CPU time that the roboRIO wouldn’t respond; the NI CSAs at Houston assumed this as well.
We re-imaged the roboRIO and everything worked correctly. Also, the roboRIO was on v16, and was updated to v17.
That’s normal, the discoverRoborio task doesn’t output any files
Glad to see you’ve found the problem, usually a reimage is best in these kinds of situations since the deploy process between LabVIEW and C++/Java is very different.
