Resolution
To install Zulu 8.23.0.3 (JDK 1.8.0_144), in your Jenkins configuration screen, you have to add a new JDK Installation using a shell script to install automatically it.
Here is the script used to install the version 8.23.0.3 (JDK 1.8.0_144). Depending of the version you want to install you may have to update the version and jdkUrl variables.
Tool Home must be the archive name without the extension (it is the directory name within the archive). In this case it will be zulu8.23.0.3-jdk8.0.144-linux_x64.
#!/bin/bash -ue
version=8.23.0.3
jdkUrl=https://cdn.azul.com/zulu/bin/zulu8.23.0.3-jdk8.0.144-linux_x64.tar.gz
jdkArchive=$(basename $jdkUrl)
jdkName="${jdkArchive%.tar.gz}"
jdkDir="$( cd -P "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
thisJdkDir=${jdkDir}/${jdkName}
if ! type wget >/dev/null 2>&1; then
echo "ERROR: Unable to run wget"
exit 1
fi
if [ -x $thisJdkDir/bin/java ]; then
JAVA_HOME="$thisJdkDir"
if $JAVA_HOME/bin/java -version 2>&1 | grep -q "$version"; then
exit 0
fi
fi
echo "Installing Zulu ${version} in ${thisJdkDir}"
rm -rf $thisJdkDir
wget --no-verbose --referer=https://www.azulsystems.com/products/zulu/downloads $jdkUrl -O ${jdkArchive}
tar -xf ${jdkArchive}
rm -f ${jdkArchive}
echo "Zulu ${version} installed in ${thisJdkDir}"
exit 0
For example if you use it with Apache Maven it will give you something like
[zulu] $ mvn --version Apache Maven 3.5.1 (094e4e31a5af55bb17be87675da41d9aeca062f3; 2017-09-10T08:42:54-04:00) Maven home: /scratch/jenkins/tools/hudson.tasks.Maven_MavenInstallation/Maven_3.5.1/apache-maven-3.5.1 Java version: 1.8.0_144, vendor: Azul Systems, Inc.
