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.

I have disabled my Ipv6 and now when I ping the roborio at roborio-3506.local I get a reply with an IPv4 address, but I still can't delpoy code and I still get the same build log:

Re: Eclipse won't connect to roboRIO
 
If you can ping the roboRIO, maybe it's a problem with eclipse specifically. Can you try disabling the firewall just to be sure that it's not blocking eclipse? Also, you can try some of the other programs like SmartDashboard (but remember to set the team number in it's preferences) to see if they can connect.

Also does the Driver Station connect on the same computer?

We have tried disabling the firewall and nothing changes. We can use SmartDashboard successfully, and we do not have the 2015 driverstation on this computer.

Re: Eclipse won't connect to roboRIO
 
I had a problem where I couldn't upload code. I fixed it by making sure that my computer was using the right ip when connected to the router. If you aren't on 10.TE.AM.23 (or any random last number) than you won't be able to connect. Double check that

The roborio uses mDNS so we shouldn't have to set a static IP. Everyone else is either uploading through mDNS or 10.35.6.2 and no one has to set a static IP, but I will try that to see how it works an follow up.

Re: Eclipse won't connect to roboRIO
 
My (Windows 7) laptop will occasionally refuse to connect to the RoboRIO. When that happens I follow these steps to get it talking again.
  • Disconnect all network connections
  • Power off the RoboRIO
  • Power on the RoboRIO
  • Wait until the AP is ready then wait about 10 seconds more
  • Connect with wifi

YMMV

I get the exam same error. Does it take long for you when you are pinging roborio-TEAM.local?

The time it takes to ping it varies, it can take as long as 500 ms or be as quick as around 5 ms.

<property file="${user.home}/wpilib/cpp/${version}/ant/build.properties"/>
I am going to try it tomorrow when I get back to the lab. But, just in case anyone just copies and pastes it and doesn't notice, make sure to change cpp to java:

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

For me it says it takes 3ms even if takes minutes...

Re: Eclipse won't connect to roboRIO
 
I feel like there is something that didn't download correctly on my computer since it works on everyone else's computer including the ones that members bring and the ones our team has.

I tried this. With both cpp and java in the line of code and neither one worked. They both gave me the same error.

I know, I feel like that happened as well because me and three other people are using Windows 8.1, two others are using Windows 7 and the last one is using a mac (not sure about his operating system's version) and one of the first things I tried was uninstalling and reinstalling eclipse and reinstalling the WPI plugins.

Re: Eclipse won't connect to roboRIO
 
I was experiencing the same problem. The wpilib jar in eclipse prompted me to update, and when I did, the problem went away. Hope this is the same for you
