TeamCity agent's show a list of "Environment Variables" under Agent Parameters but I cannot get them to update. I've added environment variables to my agent operating system, but cannot get them to refresh. I've tried restarting the agent and disabling and re-enabling the agent.

The TeamCity agent doesn't actually read environment vars from the OS. Instead it reads them from the buildAgent/conf/buildAgent.properties file on your agent machine. Down at the bottom of this file you'll see instructions on how to add new variables. Something like this:

# Environment Variables
#env.exampleEnvVar=example Env Value
env.GRADLE_HOME=/Frameworks/gradle-2.9

Once you'ce done this switch to command prompt on your agent machine, and execute something like this:

./agent.sh stop
./agent.sh start

Obviously OS dependant. There is a .bat file there for Windows.

That should get your Environment variables showing up in TeamCity.
