I have download a fresh install of TeamCity 4 and am trying to run on Linux server that sits behind a corporate firewall/proxy. From previous posts, it looks like when TeamCity is first started, it will connect back to jetbrains server and download additional plugins such as the Maven2 runner. Is there a way to configure the proxy port and user information that TeamCity uses for this purpose or is there a way to download and install the plugins manually? Or am I totally off-base here? The core problem I am having is when I look at the build runners supported by the default build agent, I only see the command line builder. Maven2 is not in the list. My build also indicates that the build agent is not compatible with my build.
