Jenkins For Building SpringBoot#

Jenkins Configurations#

Now, firstly when the Jenkins is started, you should goes to Manage Jenkins --> Manage Nodes And Clouds as the image below:

Then you can see, by default Jenkins will have an built-in node which is your real machine that you are using to run Jenkins by docker.
Then you need to go Manage Jenkins -> Global Tool Configuration as the image below

Then you scroll down to find the tag Maven. You should put a Name then choose Install automatically and then choose the Version of Maven that you want to install.

Next you scroll to tag JDK and put a name for it like JDK8. We don't need to install JDK 8 anymore because we already have JDK 8 by default inside the docker image jenkins.

Finally, you scroll to tag Git and put a Name -> set Path to Git executable as /usr/bin/git -> choose Install automatically. Click button Save.

Create Pipeline On Jenkins#

Now, we will try to create a pipeline on Jenkins for building SpringBoot project. Firstly, you go to Dashboard and click New Item.
Then you set a Name -> choose Multibranch Pipeline -> click Ok.

Next, in tag Branch Sources, you put some information about your GitHub Repository and Branch that you want Jenkins clones and builds.
Note: you can set multi branches for Jenkins Build.

Next, You scroll down and config Build Configuration and Scan Multibranch Pipeline Triggers as the image below.
Note that Script Path is the path to Jenkinsfile in your GitHub repository(your source code on GitHub).
For Scan Multibranch Pipeline Triggers choose Periodically if not otherwise run and Interval as 1 minute. Interval means when your repository has changed so the pipeline will be triggered automatically after 1 minute.
Finally click Save

Create Jenkins File In Your Repository#

So let craete a folder in the root of your repository name jenkins and a file name build.Jenkinsfile as you defined in the Jenkins Pipeline.

In the file build.Jenkinsfile. Let’s add scripts as below

build.Jenkinsfile
pipeline {
    agent any
    tools {
        maven 'Maven 3.8.6'
        jdk 'JDK8'
    }
    stages {
        stage('Build') {
            steps {
                sh 'printenv'
                sh 'ls -la'
                sh 'mvn clean install -DskipTests'
            }
        }
        stage("Run Test") {
            steps {
              sh 'mvn test'
            }
        }
    }
}

Now, let’s commit and push your code changes to your respository and check the Jenkins Pipeline, You can see It’s built successfully.

So, That’s it. Thanks and Good luck!
