Creating a Maven CICD Pipeline for Java web application is as easy as baking a cookie

In this guided hand on CICD project, you will be creating a Java web application through Azure DevOps

Section1 – Steps to create a Maven Pipeline for Java based application

Login to DevOps portal:  dev.azure.com and enter login details

2. Create + sign to start creating a “new project”  on the portal

3. Fill in the details as needed for your new project

4. An overview inside DevOps after the project is successfully created

5. Click on Repos and upload your code or import it. If you have a code on existing GIT repo, you can choose clone option for the code to be available

6. Navigate to code location and verify that the code is successfully uploaded and available

Until here we have our code-files ready in our repo to proceed further with creating a build pipeline. In the next section, we’ll look into how to create a build pipeline using a classic editor.

Section 2 –    Create a build pipeline in Azure DevOps

What is Azure pipeline ?

Azure Pipeline is a cloud service that we can use to build and test our code project automatically.

1. Click on select classic editor

2. Now you will be prompted to choose the source location of your code. I have chosen Azure repos as my code exist there. You can choose your source accordingly

3. In the Select a template screen, select Empty job. A job is a collection of steps that are runs in a sequence for the defined environment

Section 3 – Add tasks to the pipeline

We will now add new tasks to perform specific jobs and configure to run in a sequence

1. Click + sign next to Agent job 1

2. Select task and continue to add them as per the sequence defined in the image

3. Configure respective tasks for your build definition as described in the below images

4. Configure path to publish and click save and queue

5. Click run

6. After clicking run, the job is queued and will be executed one the agent gets available

7. Images showing running of the job and successful completion

8. Click on summary to verify the job status – as success. Notice that it reflects 1 published, it is the artefact which will be used during release pipeline

Section 4 – Create Release Pipeline

1. Navigate to Pipeline on the left side menu and select Releases >>> click New Release Pipeline

2. Select a Template > Empty Job

3. Add a new stage to your empty build pipeline

4. Enter the text as desired

5. Click on pipeline and select “Add an Artifact”, select the values as appropriate from the drop down on the right

6. Click Add to select Artifact

7. Click on the + sign and add the tasks as shown in the picture

13. Select task “Deploy Azure App Service”, enter the details as appropriate

14. Ensure WAR file is selected

15. Save your release. Click OK

16. Create Release and watch on screen progress for deployment

18. Navigate to Azure portal and verify that the relevant services are provisioned

19. In Azure Portal, click the URL and VOILA!! You have done it
