Building Jenkins

Jenkins version 2.0 has been successfully built and tested for Linux on z Systems. The following instructions can be used for RHEL 6.6, RHEL 7.1, SLES 11, SLES 12 and Ubuntu 16.04.

General Notes:
i) When following the steps below please use a standard permission user unless otherwise specified.

ii) A directory /<source_root>/ will be referred to in these instructions, this is a temporary writeable directory anywhere you'd like to place it.

Step 1: Install the dependencies

Following are the build dependencies for Jenkins:

  • git (RHEL6/7 and Ubuntu 16.04) or git-core (SLES11/12)
  • Maven

Dependencies Installation Notes:

  • Git can be installed on RHEL6/7 using the command below.

          sudo yum install -y git

  • Git can be installed on SLES11/12 using the command below.

          sudo zypper install -y git-core

  • Git can be installed on Ubuntu 16.04 using the command below

          sudo apt-get install -y git

  • To install Maven

For RHEL6/7 and SLES11/12 Please refer to the Maven recipe.

For Ubuntu 16.04

     sudo apt-get install -y maven
	 export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=1024m"

  • To install Java, use the command below,(Only for Ubuntu 16.04)

          sudo apt-get install openjdk-7-jdk
  	export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-s390x/jre/
Step 2: Build Jenkins

  • Get the source (clone branch 2.0)

      	cd /<source_root>/
      git clone https://github.com/jenkinsci/jenkins.git
  	cd /<source_root>/jenkins
  	git checkout jenkins-2.0

  • Build the source code using mvn command

    Comment out the nodejs plugin download and installation section in /<source_root>/jenkins/war/pom.xml file as follows for jenkins war to build succesfully.

      	<!--
  	<profile>
  	<id>node-classifier-linux</id>
  	..................................
  	..................................
  	-->
  	</profiles>
  	</project>

    Build the source

      	cd /<source_root>/jenkins
  	mvn clean install -pl war -am -DskipTests

  • To install nodejs plugin manually [optional]

    For RHEL7/RHEL6

     	sudo yum install make gcc-c++

    For SLES12/SLES11

     	sudo zypper install make gcc-c++

    For RHEL7/RHEL6/SLES12/SLES11

     	cd /<source_root>/ 
 	git clone https://github.com/andrewlow/node.git
 	cd /<source_root>/node 
 	./configure && make && sudo make install

    For Ubuntu 16.04

     	sudo apt-get install nodejs npm

  • To execute test cases [optional]

      	mvn clean install -pl war -am

    Note: User can ignore intermittent test-case failures as it does not affect the functionality (jenkins.security.DefaultConfidentialStoreTest, hudson.LauncherTest and hudson.util.io.TarArchiverTest are the test cases that fail due to wrongly set file path permissions)

    After building jenkins, a jenkins.war will be created in jenkins/war/target folder.

Step 3: Deploy Jenkins
  • Refer to the Deploy section of Apache Tomcat recipe for deploying jenkins.war on Apache Tomcat.
