与 Jenkins 的无头持续集成

问题描述

我正在尝试在 RackSpace ArchLinux 云服务器上设置 Jenkins，但我一直无法做到.

I’m trying to set up Jenkins on a RackSpace ArchLinux Cloud Server, but I’ve been unable to.

每当我尝试访问 Jenkins 站点时，都会收到此错误:

Whenever I try to access Jenkins site, I get this error:

AWT is not properly configured on this server. Perhaps you need to run your container with "-Djava.awt.headless=true"?

那么，你认为它可能是什么?

So, what do you think it might be?

我已经尝试过设置 JAVA_OPTS 环境变量，但无济于事.我还尝试使用 -Djava.awt.headless=true 执行 Java，甚至在 conf/wrapper.conf 中将其设置为 wrapper.app.parameter.3=-headless.

I’ve already tried setting JAVA_OPTS environmental variable, to no avail. I also tried executing Java with -Djava.awt.headless=true, or even setting it in conf/wrapper.conf as wrapper.app.parameter.3=-headless.

知道如何解决这个问题吗?我对这个很陌生...

Any idea how may I tackle this problem? I’m so new at this...

提前致谢！

推荐答案

终于找到解决方案.

信不信由你，其实就是安装ttf-dejavu字体的问题！

Believe it or not, it was actually just a matter of installing ttf-dejavu font!

我很惭愧...
