在Jenkins中是否有任何适当"的方法来更改系统属性?更改它们的最简单/最快的方法是什么?例如，我需要关闭无用的(在我的情况下)ping线程.

Is there any "adequate" way to change system properties in Jenkins? What is the easiest/fastest way change them? For instance, I need to turn off the useless (in my case) pinging thread.

推荐答案

如果您确实想要快速简单的方法来更改系统属性，则可以使用

If you really want a quick and simple way to change a system property, you can use the script console

System.setProperty("hudson.remoting.Launcher.pingIntervalSec", 0)

但这不会在重新启动后幸存下来.要使其永久，请将设置添加到java args.对于我(CentOS，Jenkins 2.7.1)而言，这是/etc/sysconfig/jenkins一半的行(对于其他发行版，我相信它是/etc/default/jenkins)，您应该在其中将选项添加到现有列表中，如下所示:

But that won't survive a restart. To make it permanent, add the setting to the java args. For me (CentOS, Jenkins 2.7.1) that's a line about halfway down /etc/sysconfig/jenkins (for other distributions I believe it's /etc/default/jenkins) where you should add your option to the existing list like this:

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dhudson.remoting.Launcher.pingIntervalSec=0"

做出更改后，您必须重新启动Jenkins(感谢Mark Tickner)

You'll have to restart Jenkins after you make that change (thanks Mark Tickner)
