　　Installing the GreenHopper Plugin
　　Installing GreenHopper is no different to installing any other JIRA plugin:
　　1 Download GreenHopper. If you have a .zip simply rename your file as a .jar — Internet Explorer is playing tricks on you.
　　2 Shut down JIRA.
　　3 Replace or copy the jar into the {JIRA_HOME}/plugins/installed-plugins directory.
　　clip_image001 The default {JIRA_HOME} location is C:/Program Files/Atlassian/Application Data/JIRA， if you are using Windows. Read more about the JIRA Home directory.
　　4 Remove any jira-greenhopper-plugin-*.jar from your {JIRA_INSTALL}/atlassian-jira/WEB-INF/lib directory.
　　clip_image001[1] The {JIRA_INSTALL} location will be something like C:/Program Files/Atlassian/JIRA 4.0.0， if you are using Windows. Read more about the JIRA Installation directory.
　　5 Restart JIRA.
　　安装GreenHopper插件
　　1、下载GreenHopper，如果你下载到了a.zip这类的文件，那么重命名为a.jar
　　2、关闭 JIRA
　　3、替换或者拷贝jar到 {JIRA_HOME}/plugins/installed-plugins directory.
　　注意：{JIRA_HOME}在jira/atlassian-jira/WEB-INF/classes/jira-application.properties文件中的jira.home = /usr/local/atlassian/jira/data（这是我定义的jira_HOME）。
　　4、从{JIRA_INSTALL}/atlassian-jira/WEB-INF/lib目录中移除所有jira-greenhopper-plugin-*.jar
　　5、重启JIRA
