roboRIO not found

[JohnGilb]

I've been having some trouble programming/debugging the RoboRIO. This is the tail end of the output I see in the console when attempting to deploy:

get-target-ip:
     [echo] Trying Target: roboRIO-488.local
Unknown host: roboRIO-488.local
     [echo]  roboRIO not found via mDNS, falling back to static USB
     [echo] roboRIO not found via USB, falling back to static address of 10.4.88.2

BUILD FAILED
C:\Users\John\wpilib\java\current\ant\build.xml:45: Assertion failed boolean test.
roboRIO not found, please check that the roboRIO is connected, imaged and that the team number is set properly in Eclipse

I can ping roboRIO-488.local successfully. I can also read the files on the roboRIO via FTP.

In Window->Preferences->WPILib Preferences, my team number is set to 488.

The roboRIO has been imaged with the v23 image (and I can confirm with the tool). I can also see and operate the robot via the Driver Station.

By plugging in the USB cable, I am able to program the robot. Also, the debug environment seems to only try connecting to roborio-488.local, and doesn't work via USB.

Any idea what's going on?
