This document provides steps to set up Jenkins for continuous integration, including installing Java, Git, and configuring a GitHub account. It then explains how to create a Jenkins job that will build a project from a GitHub repository, run tests, and generate code coverage reports on each commit. The job is configured to pull code from GitHub, run Maven goals to build and test the project, and publish JUnit test reports, JavaDocs, and a Cobertura code coverage report.

1. First Step to
Jenkins

2. Prepare Env
Java
Apache Maven
Git
Github

3. Prepare Env
Java
Git
Github.com Account
Config SSH Key

4. Install Java
Download from Oracle
Testing
$javac -version
$java -version

5. Install Git
Download from http://git-scm.com/
$apt-get install git-core
Testing
$git —version

6. Create Account at
Github
Goto http://www.github.com

7. Config SSH Key
Create SSH Key
$ssh-keygen
Copy your SSH Key from ~/.ssh
id_rsa => private key
id_rsa.pub => public key

8. Copy key to Github
Goto account setting => SSH Keys

9. Add your public key

10. Fork Example Project
Project at https://github.com/up1/
demo_jenkin_project

11. Fork

12. Testing with clone
$git clone git@github.com:<username>/
demo_jenkin_project.git

13. Setup Jenkins
Download from http://jenkins-ci.org/

14. Start Jenkins
$java -jar jenkins.war

15. Welcome Jenkins
http://localhost:8080

16. Manage Jenkins

17. Main Configuration

18. Config Jenkins
JDK
Apache Maven
Notification
Git plug-in

19. Config JDK
Default => Download from Oracle

20. Config JDK
Use JAVA_HOME

21. Config Maven
Default => Download from web

22. Config Maven
Use MAVEN_HOME

23. Notification

24. Setup Git
Install Git plug-in
Goto Manage Jenkins
Manage Plug-in

25. Git Plug-in

26. Installing

27. Create First Build Job
New Job/Item
Pull code from GitHub.com
Scheduling to build job
Build process
Report

28. Step 1 New Item

29. Step 2 Create Job

30. Pull code from Github
Set git repository

31. Config Build Trigger
Build after project
Build period
Poll SCM

32. Poll SCM
minute (0-59)
hour (0-23)
day of month (1-31)
month (1-12)
day of week (0-7)

33. Poll SCM
Every minute => * * * * *

34. Build process
Build with maven goal

35. Build process
clean package

36. Create Report
Post Build Action => JUnit Report

37. Achieve Artifact

38. Try to Build

39. See Result

40. Test Report

41. See Result

42. Add JavaDoc ?
How To ?

43. Add JavaDoc
Post-build => Publish JavaDoc

44. You MUST got ERROR
Try to add javadoc:javadoc
add path of JavaDoc
./target/site/apidocs
And build again !!!

45. Result of JavaDoc

46. JavaDoc

47. Add Cobertura
What is Cobertura ?
Code coverage utility for Java
http://cobertura.github.io/
cobertura/

48. Add Code Coverage
Use Cobertura plug-in
http://cobertura.github.io/cobertura/

49. Maven Project
pom.xml
Config plug in to generate
cobertura.xml

50. pom.xml for Cobertura
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>
<configuration>
<formats>
<format>xml</format>
</formats>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>cobertura</goal>
</goals>
</execution>
</executions>
</plugin>

51. Add goal on Build
process
cobertura:cobertura

52. Add post-build
Publish Report

53. Advanced…

54. Build and See Result

55. Build and See Result

56. Coverage Report

57. Report by file

58. Welcome to
Jenkins
