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:

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

So, what do you think it might be?

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.

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

Thanks in advance!

Are you running Sun's Java or OpenJDK? – Blender Nov 13 '11 at 04:48 — Blender, Nov 13 '11 at 04:48

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

This worked for me on CentOS with OpenJDK 1.7 but only after I also installed fontconfig. – Todd Jan 18 '13 at 00:03

OpenSUSE: `zypper install dejavu-fonts` – Jesse Glick May 21 '14 at 17:07
Seconding that a clean CentOS 7 with Adopt OpenJDK 11 needed fontconfig installed, which has dejavu-sans-fonts as a dependency. Just dejavu-sans-fonts by themselves didn't do it. – Hammer Bro. Jul 26 '21 at 20:46

Finally found a solution.

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

I’m ashamed...

Don't be!! It can happen to anyone! The Headless error can be very tricky to understand the route cause! – sdmythos_gr Nov 17 '11 at 12:53

In my case (also Arch Linux here) having ttf-dejavu did not help when tried to run Jenkins with OpenJDK. Only after installing Oracle JDK Jenkins started without the specified error. – jmu Feb 05 '12 at 16:55

Installation of java-1.6.0-openjdk resulted in the following dependency's:

fontconfig
libXfont
libfontenc
ttmkfdir
xorg-x11-font-utils
xorg-x11-fonts-Type1

After the installation of those packages and a restart of jenkis, everything worked as designed.

Oracle java7 also need this dependencies, its not just openjdk – higuita Sep 20 '12 at 17:20
@Zab0815, just curious, what distro that you tried on and how did you get such a list of dependency? I just tried on both CentOS 6.3 and Fedora 17, with both java-1.6.0-openjdk and java-1.7.0-openjdk. I used yum deplist together with some shell filters. I got quite different output, but yours works! Thanks! – user183394 Oct 15 '12 at 18:41
This actually worked. Thanks a lot! – Serban Cezar Nov 24 '21 at 18:54

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

Installed ttf-dejavu package
Installed fontconfig packages
added to /etc/conf.d/tomcat7:

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

Installing `ttf-dejavu` and `fontconfig` worked for fixing it on WSL – JamMaster Apr 02 '20 at 14:44

For me installing the fonts didn't help at all. For me it actually missed the fontconfig package.

I had the same problem.
I'm using MobaXterm as a terminal for my linux account, and for me the solution was in MobaXterm. I had to enable X11 under Settings --> Configurations.

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.

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

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