Beginners Guide to Jenkins

In this blog we will be learning how to use Continuous Integration tools to deploy Projects, Here I will be using Jenkins as CI and Maven as build tool to deploy Spring MVN Based Applications.
STEP 1:
You can Install Jenkins through yum/apt-get for your Linux/Redhat Distributions, but I prefer to install jenkins as a home user so that it can access my tools like java,maven,capistrano,ruby,pscp and many different tools.

My Home directory here is /home/rails

Jenkins will be installed under /home/rails/.jenkins

To do this I will download the Jenkins.war file from jenkins repo

STEP 2 :
Execute the war file using this command

java -jar jenkins.war --httpPort=8080

You will view the following lines

Nov 05, 2015 1:14:43 AM hudson.WebAppMain$3 run
INFO: Jenkins is fully up and running

Access Jenkins through localhost:8080
You should View a Wonderful Jenkins Dashboard.

STEP 3 :

Create a User who can create jobs and build those, Let me make it easier for you:
•Click on Manage Jenkins => Configure Global Security
•Enable Security => Jenkins Own user Database.
•Under Authorization part, select Matrix based Security, For Anonymous User Under View select only Read Permission
•Now Click on Add and create a user named Admin and Grant All Access
•Click Save and Apply
•You will be redirected to Set up page enter your password and click Save.

Step 4:

Manage Plugins:

By Default Jenkins comes in with prebuilt plugins like svn, maven,scp for installing extra plugins you can go to availables tab and install.

Step 5:

Accessing Repository to download source code and build
•Here I will be using SVN & SSH
•As I am in my home directory I will be using my ~/.ssh/id_rsa Keys for Authentication
•Click on Add Credentials => Global Credential and enter your credentials
•Repo url: svn+ssh://svn@svn.corporate.com/projects
•SSH Authentication
Username : svn
Passphrase: ****** (Null if no Passphrase)
Private Key : Upload your id_rsa Key

Step 6:

Click on Create Job:
•Type Project Name
•Enter SVN Repo details
•Build => Invoke Top Level Maven Target
•Use Maven Version as Default
•Goal : clean -Dmaven.test.skip=true package -P prod
•Apply and Save.
Now Its Done.
If you need to send the build to some other location Enter your script in command shell this would do the Work.
Step 7:

Click on Build Now, The Build Should Work for you.

Now it should show you a success message.
