3. Go to the "Build" tab, using the drop down menu, to select a step.
Normally like a web app, you can select "Excute Shell" / "Excute Windows batch command". 
Here, because we use java application as an example, so we select "Invoke top-level Maven targets".

So now jenkins will do the following steps:
  • Go to our github, clone the source code and put the code inside "~/.jenkins/Workspace/atomsphere" folder.
  • Output file (if any) will be also put inside this folder.
Usually the output files will be some file we want to use, for example a web app, the output might be the bundle files that we want to served. 
Now everytime you click "Build Now" button, it will re-generate new files and discard the previous files. But we might want to keep history instead of throw those away.
 
7. Archive previous version files
We can actaully choose which files (folder) actually we want to keep. For web app, it might be just one "dist" folder.
Here we want to keep jar file which generated by comiler.

  10. Those jenkins job are actually saved into a config.xml file inside "workspace/[job_name]" folder. 
If anything change on this file manully, you can also click "Reload Configuration from Disk" to get latest changes.
