Jenkins/Hudson - accessing the current build number?

Question

I have a report file I'm generating, and I would like to be able to add the current build number to that file within a Jenkins job. Is there an environment variable or plugin I can use to get at the current build number?

Answer 1

BUILD_NUMBER is the current build number. You can use it in the command you execute for the job, or just use it in the script your job executes.

See the Jenkins documentation for the full list of available environment variables. The list is also available from within your Jenkins instance at http://hostname/jenkins/env-vars.html.
