关于jenkins更新后， job description只显示html代码的问题

相信很多人在jenkins 更新到1.553版本（及以上版本）后，发现自己之前在job description写好的html代码，都失效了，现在显示的都是html源码。

我看了1.553版本changelog，发现有以下改动（见标红）

What's new in 1.553 (2014/03/02)

•     Build history widget only showed the last day of builds.    (Due to JENKINS-20892, even with this fix at most 20 builds are shown.)    (issue 21159)  
•     Random class loading error mostly known to affect static analysis plugins.    (issue 12124)  
•     After restarting Jenkins, users known only from changelogs could be shown asFirst Last [e-mail]_, breaking mail delivery.    (issue 16332)  
•     CLI build -s -v command caused 100% CPU usage on the master.    (issue 20965)  
•     Slave started from Java Web Start can now install itself as a systemd service.  
•     Split the “raw HTML” markup formatter out of core into a bundled plugin.  
•     Do not show Maven modules and matrix configurations in the Copy Job dialog.    (issue 19559)  
•     Fix autocompletion for items in folders.    (pull request 1124)

 

原来在这次更新后，Configure Global Security页面有个Markup Formatter， 将它由Escaped HTML改成Raw HTML。

 

然后再去修改job description就好了
