So this is been going on for a while. Everything works when I use the build in outbound/inbound change set to deploy code form Sandbox to Production. And Fails every time trying to deploy the exact same code using either Force.com IDE (Eclipse) or Mavensmate. I get test class failure. "No such column ..... on entity". But the test class pass just fine when I run them in developer console. Please help, thanks.
Two things I can think of:
One, your package.xml file is out of date and you need to refresh - perhaps you are only refreshing selected parts of it. Do a system wide refresh.
Two, make sure you are at the latest possible api level - perhaps the object you are deploying has changed with an api update and your older version in package.xml contains an out of date version (with fields that are no longer there)
