Is that the whole lot for appium? It stops in weird point.
It looks like you have a problem with your adb. Check that adb is running and the device is connected.
try
adb devices
It should show your Android device (and it shouldn't be offline or anything like that).
If nothing shows, try:
adb kill-server
adb start-server
And then again try the adb devices.
The error in eclipse you see is purely because you stop appium server.
