Starting 1.302, Hudson has a built-in CLI client that allows you to access Hudson from a script or from your shell. This is convenient for automation of routine tasks, bulk updates, trouble diagnosis, and so on.

Obtaining CLI

Hudson CLI is distributed inside hudson.war. Download it from In theory, the CLI jar is dependent on the version of Hudson, but in practice, we expect to be able to retain compatibility between different versions of Hudson.

Running CLI

The general syntax is as follows (the design is similar to tools like svn/git):

java -jar hudson-cli.jar [-s HUDSON_URL] command [options...] [arguments...]

HUDSON_URL can be specified via the environment variable $HUDSON_URL. The 'help' command will give you the list of the available commands, which depends on the server you are talking to.
