My approach to this answer will be to first mention how to create Jenkins job. Go to Jenkins top page, select “New Job”, then choose “Build a free-style software project”.
Then you can tell the elements of this freestyle job:
* Optional SCM, such as CVS or Subversion where your source code resides.
* Optional triggers to control when Jenkins will perform builds.
* Some sort of build script that performs the build (ant, maven, shell script, batch file, etc.) where the real work happens.
* Optional steps to collect information out of the build, such as archiving the artifacts and/or recording javadoc and test results.
* Optional steps to notify other people/systems with the build result, such as sending e-mails, IMs, updating issue tracker, etc..
