一个基于java的程序-Jenkins

What is Jenkins?

Jenkins is an award-winning application that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Jenkins focuses on the following two jobs:
  • Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Jenkins provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity.
  • Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Jenkins keeps those outputs and makes it easy for you to notice when something is wrong.

Features

Jenkins offers the following features:
  1. Easy installation: Just java -jar jenkins.war, or deploy it in a servlet container. No additional install, no database.
  2. Easy configuration: Jenkins can be configured entirely from its friendly web GUI with extensive on-the-fly error checks and inline help. There's no need to tweak XML manually anymore, although if you'd like to do so, you can do that, too.

Test Drive

Launch Jenkins through Java Web Start for a test drive. Once it launches, visit http://localhost:8080/ to get to the dashboard. Any configuration that you do with this Jenkins will be stored in ~/.jenkins, so your data will survive through Jenkins process restart.

Installation

To run Jenkins, you need the Java Runtime Environment (JRE) 1.6 or later. After you download jenkins.war, you can launch it by executing java -jar jenkins.war. This is basically the same set up as the test drive, except that the output will go to console, not to a window.
Alternatively, if you have a servlet container that supports Servlet 2.4/JSP 2.0 or later, such as Glassfish, Tomcat 5, JBoss, Jetty 6, etc., then you can deploy jenkins.war as you would any WAR file. See this document for more about container-specific installation instruction.
Once the war file is exploded, run chmod 755 jenkins in the exploded jenkins/WEB-INF directory so that you can execute this shell script.
If you're running on Windows you might want to run Jenkins as a service so it starts up automatically without requiring a user to log in. The easiest way to achieve this is to simply download and install Jenkins via the native Windows installer, which can be found on the Jenkins main page. Just download the .zip file, unpack it, and click through the install wizard. The wizard both installs Jenkins and sets up the Jenkins Windows service for you.
Another way to run Jenkins as a service is to first install Tomcat as a service and then deploy Jenkins to it in the usual way. Another way is to use the Java Service Wrapper. However, there may be problems using the service wrapper, because the Main class in Jenkins in the default namespace conflicts with the service wrapper main class. Deploying inside a service container (Tomcat, Jetty, etc.) is probably more straightforward, even for developers without experience with such containers.
