Eclipse won't connect to roboRIO
 

My team, 3506, has been using netbeans to upload to code to our robots in previous years, however the roboRIO no longer supports plugins for netbeans and my team has had to switch to using eclipse. We code our robots in Java and after going through the long process of setting up the roboRIO for Java attempted to upload some code. Here's the problem: three of the six people on my programming team can upload code to it (two using roboRIO-3506.local and one using 10.35.6.2), but the rest of can't. The three of us that can't upload code can ping the roborio at both addresses and consistently get replies, but whenever we try to upload code from eclipse we all get the same error message: roboRIO not found, please check that the roboRIO is connected, imaged and that the team number is set properly in Eclipse. Our team numbers are all properly set, and we know that it is properly imaged and connected because the others can upload code and we can ping it. Does anyone have any possible solutions?

Have you guys tried installing Java onto the RoboRio??

Re: Eclipse won't connect to roboRIO
 

Yes we have. We were having trouble installing java onto it, but we managed to do it. This allowed three of us to deploy code, but the rest of us are left scratching our heads.

Re: Eclipse won't connect to roboRIO
 

Can they upload code through the USB connection?

Re: Eclipse won't connect to roboRIO
 

Those that can upload code have not tried to do so via USB and those that can't upload have tried, but with no results.

Re: Eclipse won't connect to roboRIO
 

Your operating system might be blocking Eclipse's communications with the roboRIO. I know I had to accept a Warning when I first uploaded code. Try disabling your firewall and see if that fixes anything.

EDIT: Also please post a full build/run log

Re: Eclipse won't connect to roboRIO
 

Unfortunately, we have already tried that, I disabled my anti-virus software and my firewall and nothing changed.

Re: Eclipse won't connect to roboRIO
 

Have y'all re-imaged the roboRIO?

Re: Eclipse won't connect to roboRIO
 

From the computer that you are trying to push code from can you ping the roboRIO at roboRIO-3506.local or 10.35.6.2. I am trying to figure out if its an eclipse problem or a computer problem.

Re: Eclipse won't connect to roboRIO
 

I realize this isn't exactly the answer you're looking for.

But I wanted to repeat the note I saw above about using USBLAN over the USB cable to program and debug the RoboRIO. This has worked every time I've tried it, it's very reliable in my experience.

We haven't yet found a completely reliable way to connect over wifi to the RoboRio. It works many times, but not all the time.

Also, make sure that if connecting over wifi to the roborio, that you have disconnected from any other wifi connection (for instance, the wifi connection you use to access the Internet). Also, we have found that even after disconnecting from another wifi connections, we sometimes have to disconnect and then reconnect to the roborio's Wifi connection to get things to work.

Hope that helps....

Re: Eclipse won't connect to roboRIO
 

Yes we have imaged the roborio.

Re: Eclipse won't connect to roboRIO
 

Yes I can ping it at both addresses.

Re: Eclipse won't connect to roboRIO
 

I think your problem is mDNS is failing. See thread http://www.chiefdelphi.com/forums/sh...d.php?t=132597 where this is discussed at some length.

The root cause appears to be your PC and the RoboRIO deciding they want to use IPv6 instead of IPv4 -- the mDNS lookup is returning a v6 address instead of v4. This unfortunately doesn't work for the Eclipse ANT script I think or for the DS.

The solution we found was to disable IPv6 on the Laptop/PC (or Mac presumably) for that interface. Couldn't figure out how to disable it on the DLink. Presumably you could kill it on the RoboRIO in Linux config but I don't know offhand how to do that.

Re: Eclipse won't connect to roboRIO
 

My team ran into the same problem in a C++ environment. We ended up having to add the below line of code to our build.xml file at the bottom of the rest of the "property file" lines (including this one, we had 3), clean project, and build. Not sure if it'll work for you guys, but I hope it does!

<property file="${user.home}/wpilib/cpp/${version}/ant/build.properties"/>
