Eclipse UI测试在Redhat Jenkins服务器上使用gtk_init_check（）失败

当通过Jenkins在Redhat服务器（6.7）上对Eclipse运行Tycho UI测试时，发生下面的异常。我知道一个图形子系统必须安装并运行，但是我的设置似乎有些不妥。我已经通过“yum groupinstall Desktop”安装了GTK。Eclipse UI测试在Redhat Jenkins服务器上使用gtk_init_check（）失败

虚拟桌面必须运行。对此可以使用Xvfb，如http://www-01.ibm.com/support/docview.wss?uid=swg21421214所述。在Redhat上可以使用：

yum install xorg-x11-server-Xvfb 
Xvfb :5 -screen 0 1280x1024x8 -fbdir /tmp & 
export DISPLAY=:5 

显示的数字可以任意选择。在Jenkins作业中，环境变量也必须设置（通过set-env插件）。

为了在所有作业中启用这个描述如下的脚本：https://superuser.com/questions/319040/proper-way-to-start-xvfb-on-startup-on-centos应该使用chkconfig进行设置。最后，环境变量DISPLAY应该可通过添加一个shell脚本来/etc/profile.d/在其中包含唯一的行：

export DISPLAY=:5 

试验期间在我设置的默认运行级别5/etc/inittab中/但我没有进一步研究这是否是绝对必要的。
