Run commands

Use Docker to build a Jenkins plugin

1. Check out a Jenkins plugin from GitHub

   $ git clone git@github.com:jenkinsci/configuration-as-code-secret-ssm-plugin.git
   $ cd configuration-as-code-secret-ssm-plugin

2. Build the plugin. Change the maven tag to something like 3-jdk-8 or 3-jdk-11 if you run into errors, as some plugins only build with one JDK version.
   • Run as a non-root user

Below is an example to explain:

vagrant@devbox:~/foo$ mkdir bin
