Setting up Hudson CI for GWT Development

GWT development requires a 32 bit Sun JDK.

We decided to do this by using a 32 bit VM, which could be moved to another server at a later date.

1. Install VMWare Player (Ensure networking is enabled during installation)
2. Download a 32 bit ubuntu ISO (or 32 bit Debian)
3. Create a new VM from the ISO.
4. Enter VM and establish your ipaddress.
5. Add hudson repo to /etc/apt/sources

   deb http://hudson.gotdns.com/debian binary/
   

6. Install Sun JDK

   apt-get install sun-java6-jdk 
   update-alternatives --config java
   update-alternatives --config javac

7. Install Tomcat

   apt-get install tomcat6
   apt-get install tomcat6-admin
   

   Modify /etc/tomcat/tomcat-users.xml and add
   <user username="admin" password="" roles="manager,admin"/>
   (or add a password and add password to ~/.m2/settings.xml)
   Set Tomcat security off
   

   sed -i "s/TOMCAT6_SECURITY=.\+/TOMCAT6_SECURITY=no/" \
   /etc/default/tomcat6
   

   Increase Tomcat default memory allocation in /etc/defaults/tomcat6
   JAVA_OPTS="-Djava.awt.headless=true -Xmx1024M -Xms1024m"
   
8. Install Hudson

   apt-get install hudson
   

9. Change Hudson port and ajpport by editting /etc/init.d/hudson to add

   HUDSON_ARGS="--httpPort=8081  --ajp13Port=8102" 

10. Install Apache

    apt-get install apache2
    a2enmod proxy
    a2enmod proxy_http

11. Setup /etc/apache2/httpd.conf (or similar)

servername hudson
ProxyPass   /  http://localhost:8081/
ProxyPassReverse  /  http://localhost:8081/
ProxyRequests   Off
<Proxy http://localhost:8081/*>
Order deny,allow
Allow from all
</Proxy>

12. Install Maven

    apt-get install maven2

13. Configure Hudson
    • setup smtp
    • set MAVEN_HOME to /usr/share/maven2
    • set email from address
    • set url to ip address
14. Download GWT toolkit 1.7.1 and extract then install gwt-dev-linux.jar to your local repo

    mvn install:install-file \
    -DgroupId=com.google.gwt -DartifactId=gwt-dev \
    -Dversion=1.7.1 -Dclassifier=linux \
    -Dpackaging=jar -Dfile=gwt-dev-linux.jar

15. Add individual projects to Hudson
