Stream logs to the console from the latest build of a project in Jenkins

Features:

• Shows logs from the latest build, even when a new build starts
• Scrolls automatically if the log is at the bottom
• Scroll forward and back through the log in the terminal with arrow keys or page up/page down
• Supports scrolling with the mouse wheel if your terminal does (tested in iTerm2)

Download the appropriate binary for your operating system from https://github.com/jashort/jenkins-log-streamer/releases and place it in the path.

jenkins-log-streamer --url https://jenkins.example.com/job/YourProject/ --user YOUR_USERNAME --token YOUR_TOKEN

Parameters:

• --url: The URL to your job in the Jenkins UI, without a specific build number. For example:
  • A multibranch pipeline in the "Projects" folder, the "demo" project on the "main" branch: https://jenkins.example.com/job/Projects/job/demo/job/main/
  • In a regular project in the root: https://jenkins.example.com/job/YourProject/
  • Using http on a nonstandard port: http://jenkins.example.com:8080/job/YourProject/
• --user: The username you use to log in to Jenkins
• --token: Your Jenkins API Token. After logging in to Jenkins, click on your username in the upper right corner, then "Configure", then "Add New Token" under "API Token".

--user and --token may be set in the environment variables JENKINS_USER and JENKINS_TOKEN instead of setting them with command line arguments.
