jenkins不显示统计图

java.lang.NoClassDefFoundError: Could not initialize class org.jfree.chart.JFreeChart

Somebody helped me to solve it here : https://groups.google.com/forum/#!topic/jenkinsci-users/o_Dr7Tn0i3U

It’s not a bug in Jenkins but a miss-configuration. Anyway I couldn’t find it in any knowledge base. Maybe adding this solution in JIRA is enough … but let me suggest you to try to add it somewhere in plugin’s documentation, for example on “Configuration” section found here https://wiki.jenkins-ci.org/display/JENKINS/Performance+Plugin

The solution is just adding

-Djava.awt.headless=true

I’m running Jenkins as a webapp on my Tomcat, so I just added this line to my /opt/tomcat/bin/catalina.sh :

CATALINA_OPTS=-Djava.awt.headless=true

Headless模式是系统的一种配置模式。在该模式下,系统缺少了显示设备、键盘或鼠标。Headless模式虽然不是我们愿意见到的,但事实上我们却常常需要在该模式下工作,尤其是服务器端程序开发者。因为服务器(如提供Web服务的主机)往往可能缺少前述设备,但又需要使用他们提供的功能,生成相应的数据,以提供给客户端(如浏览器所在的配有相关的显示设备、键盘和鼠标的主机)。
