Headless continuous integration with Jenkins

Question

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

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

Answer 1

On my fedora 17 64Bit machine, I had OpenJDK 1.7 installed and I yum installed Jenkins which was having the same issue. Setting up -Djava.awt.headless=true did not help.

Finally solved the issue by installing dejavu-sans-fonts:

yum install dejavu-sans-fonts

Answer 2

Having an ArchLinux 64 bit headless server, I have successfully configured jenkins to work by following steps:

1. Installed ttf-dejavu package
2. Installed fontconfig packages

3. added to /etc/conf.d/tomcat7:

   CATALINA_OPTS="-Djava.awt.headless=true"

Answer 3

On Linux Server release 6.2 (Santiago) , you just need to specify below command.

export CATALINA_OPTS="-DJENKINS_HOME=/opt/itmsetup/apache-tomcat-6.0.37/jenkins -Xmx750m -Djava.awt.headless=true"                           

this has solved my problem.

Answer 4

By adding CATALINA_OPTS="-Djava.awt.headless=true" in setclasspath.sh file of tomcat/bin directory solved the problem.

Answer 5

pacman -S ttf-dejavu

fixed it for my Archlinux box

Answer 6

Installing openjdk-7-jre-headless and ttf-dejavu made the difference for me on Ubuntu 12.04 LTC (Precise). The fonts are referenced by the font setup of the Java installation and the OpenJDK 7 package depends on libfontconfig1 and will thus actually use the fonts.

I'm using Jenkins from http://pkg.jenkins-ci.org/debian/ and by default you will get openjdk-6-jre-headless since the jenkins package depends on default-jre-headless, which in turn pulls in openjdk-6-jre-headless.

You can swap the packages using

$ aptitude install openjdk-7-jre-headless
$ aptitude remove default-jre-headless openjdk-6-jre-headless
