Remote command failed with exit status 1

Hey, guys!

We've been trying to deploy our Java code to our roboRIO from a MacBook Pro. However, every time we try, it spits out this log and won't complete:

Code:

Could someone please help us figure out what we're doing wrong? Thanks!

Re: Remote command failed with exit status 1

No, it's sucessful. It just couldn't kill the robot code, most likely because it wasn't already running.

To clarify, your code was successfully uploaded to the roboRIO. The error you are seeing was that it tried stop any robot code already running but didn't see any.

Re: Remote command failed with exit status 1

Why does our driver station still display negative under "robot code," then? Are we having a different problem I don't know about?

Your code is likely crashing. Are you getting any message in the DS Messages window?

Re: Remote command failed with exit status 1

I got the following message in the DS message window:

This is telling you that your code is crashing on line 90 because the SmartDashboard value you are getting doesn't exist. You can either surround those gets by try/catch, or add a default value like you used other places.
