How to setup Jenkins for a Maven project

This blog post shows how to configure the maven project in Jenkins. Follow these steps for the Jenkins Maven project configuration:

Step 1 – Starting Jenkins
a) Download Jenkins Zip file and extract it(i have downloaded for windows as i am setting it up on windows7)

b) In cmd go to the path you have extracted Jenkins (eg.C:\Program Files (x86)\Jenkins)


c) To start the Jenkins, run the command jenkins.exe start
-To restart the Jenkins: Jenkins.exe restart
-To stop the Jenkins: Jenkins.exe stop

d) By default, it will open up on 8080 port as localhost:8080 (make sure nothing else is running on port 8080)



Step 2 – Creating and configuring user on Jenkins
a) To create a user go to Manage Jenkins->Manage Users->Create User->Provide the required information



b) Go to Manage Jenkins->Configure Global Security
-Check Enable security
-In Security Realm, select Jenkins own user database and check Allow users to sign up
-In authorization, there are multiple options select as per requirement
-Save once done


Step 3 – Configuring System
a) Go to Manage Jenkins->Configure System

b) Configure JDK
-Give the JDK name
-JAVA_HOME : C:\Program Files\Java\jdk1.7.0_45

c) Maven configuration
-Give a maven name
-MAVEN_HOME : C:\apache-maven-3.2.5\apache-maven-3.2.5-bin\apache-maven-3.2.5

d) Global Maven_OPTS
–Xmx512m
–XX:MaxPermSize=128m

e) Save once done


Step 4 – Adding Plugins
a) Go to Manage Jenkins->Add Plugins

b) Install the plugins which are required, Eg. GIT client plugin: which Shared library plugin for other Git related Jenkins plugins, GIT plugin: This plugin integrates GIT with Jenkins, etc.

Step 5 – Creating jobs
a) Go to New Items->Give a project name in “Item name” field->select Maven project->click OK

b) Now configure the job
-Provide the description
-In Source Code Management, there are options for CVS project, Git etc, select the one which is required



– In Build Triggers, there are multiple options like “Build when a change is pushed to GitHub”, “Poll SCM”, “Build whenever a SNAPSHOT dependency is built” etc, select the required one
– Give the path of your pom.xml file in Build Root POM
– Give “Goals and options“ take a use case where the requirement is to install the code then give ”clean install”



c) Configure the job as in the screenshot and don’t forget to save
d) In the same way, create another job(4503_deploy)
e) Suppose the requirement is creating two jobs, one(4502_deploy) for deploying the code on author instance 4502 and if it’s built is successful than it should run its downstream job(4503_deploy) for deploying code on publishing instance.
f) Now configure the job “4502_deploy”, In Post Steps select “Run only if the build succeeds”
g) In Post Build Action, add post-build action and give the job name(4503_deploy) in “Projects to build


 

Step 6 – Build the jobs
Now build the job “4502_deploy”, on successful completion “4503_deploy” will trigger automatically and hopefully, jobs will be successful!!!

Following these steps above, you will be able to configure your Maven project over Jenkins.
