Help me compile a Java project

I have modified a little code in an open source Jenkins plugin. I don't know how to compile it so that I can use it on my Jenkins server. 1. Show me how to compile it via screen sharing. 2. Show me how to debug it. I don't have Jenkins installed locally. 3. Help me resolve any environmental issues that I might have. I don't expect many here, I have IntelliJ and Android Studio. I can compile using Android Studio. 4. Help me install it on my Jenkins server. You shouldn't have to write any code to complete this job.
