Setting up Jenkins on SAP Monsoon

Follow the initial setup and install guide, replacing the "hudson" user by a "jenkins" user: https://wiki.wdf.sap.corp/wiki/display/LeanDI/Jenkins+Setup+on+Monsoon+Ubuntu+Image

As mail host, use mail.sap.corp.

I added a jenkins_sapsailing user to our internal git repository at ssh://git.wdf.sap.corp:29418/SAPSail/sapsailingcapture.git, generated an ssh-key for user jenkins using the ssh-keygen command and added the following to ~jenkins/.ssh/config:

  Host git.wdf.sap.corp
    User jenkins_sapsailing
    HostName git.wdf.sap.corp
    IdentityFile ~/.ssh/id_rsa

The following additional packages needed to install using apt-get install ...

libxrender1
libxtst6
libXi

The Monsoon instance on which I did this for the first time can currently (2015-07-29) be reached at http://mo-11705429d.mo.sap.corp:8080/jenkins (IP address 10.97.23.55).

Add the following to the Maven configuration file at /home/jenkins/.m2/settings.xml:

        <proxies>
           <proxy>
              <id>SAP-proxy</id>
              <active>true</active>
              <protocol>http</protocol>
              <host>proxy.wdf.sap.corp</host>
              <port>8080</port>
              <nonProxyHosts>*.sap.corp|nexus</nonProxyHosts>
            </proxy>
        </proxies>

toolchains.xml and Maven version

To avoid the warnings that the Bundle-RequiredExecutionEnvironment doesn't match the compiler version, the Maven construct of ~/.m2/toolchains.xml can be used. However, the Maven version 3.3.3 built into Jenkins doesn't seem to properly respect the toolchains.xml file under /home/jenkins/.m2/. Installing Maven using apt-get install maven results in a Maven 3.0.5 being installed (is this sufficiently new?). Running from the command line or configuring this external maven version in Jenkins does the job.

Well, almost: the toolchains.xml file must point to the jre/ subdirectories, not the main JDK directories. This is pretty counter-intuitive and inconsistent with all examples found of the the toolchains.xml uses. Here is the toolchains.xml content that now is under /home/jenkins/.m2 and which works:

<?xml version="1.0" encoding="UTF8"?>
<toolchains>
  <!-- JDK toolchains -->
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.6</version>
      <id>JavaSE-1.6</id>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>/usr/java/jdk1.6.0_51/jre</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.7</version>
      <id>JavaSE-1.7</id>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>/usr/java/jdk1.7.0_80/jre</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.8</version>
      <id>JavaSE-1.8</id>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>/usr/java/jdk1.8.0_51/jre</jdkHome>
    </configuration>
  </toolchain>
</toolchains>

Git access

There is now HTTPS git access on https://git.sapsailing.com/git which maps to the Git repository at /home/trac/git. Valid user accounts for HTTP basic authentication are provided in /etc/httpd/conf/passwd.git which can be manipulated using the htpasswd tool. One default user replicate has been established to mirror the repository to the SAP-internal Git at git.wdf.sap.corp.
