Jenkins CI is a popular open source continuous integration tool. Jenkins can be used to build and test software projects continuously. Jenkins can be integrated with other tools such as Git, SVN, and Artifactory.
In this Jenkins CI Cd Pipeline tutorial, we will show you how to set up a Jenkins CI Cd pipeline. We will be using the Jenkins Git plugin, Jenkins SVN plugin, and Jenkins Artifactory plugin.
The Jenkins Git plugin can be used to clone a Git repository and build a project. The Jenkins SVN plugin can be used to clone a SVN repository and build a project. The Jenkins Artifactory plugin can be used to retrieve artifacts from an Artifactory server.
We will be using the following Jenkins CI Cd pipeline:
1. Clone the Git repository.
2. Build the project.
3. Retrieve the artifacts from the Artifactory server.
Let’s get started.
1. Clone the Git repository.
We will first clone the Git repository. We can do this by going to the Jenkins dashboard and clicking on New Job. We then select Git from the Source Code Management section and click on Clone.
We then enter the URL of the Git repository and click on Clone.
2. Build the project.
We will now build the project. We can do this by going to the Jenkins dashboard and clicking on New Job. We then select Build from the Jenkins CI Cd pipeline section and click on OK.
We then enter the name of the project and the URL of the Git repository. We then select the branch of the project that we want to build and click on Build Now.
3. Retrieve the artifacts from the Artifactory server.
We will now retrieve the artifacts from the Artifactory server. We can do this by going to the Jenkins dashboard and clicking on New Job. We then select Artifact from the Jenkins CI Cd pipeline section and click on OK.
We then enter the name of the project and the URL of the Artifactory server. We then select the repository of the project and click on OK.
We can then select the artifacts that we want to download and click on Download.

How do you explain CI CD pipeline in Jenkins?
CI (continuous integration) and CD (continuous delivery) pipelines are essential parts of a modern software development process. In this article, we will explain how to set up a CI CD pipeline in Jenkins.
First, let’s take a look at what a CI CD pipeline consists of. A typical CI CD pipeline consists of the following stages:
1. Source code repository
2. Build server
3. Build script
4. Test server
5. Test script
6. Deployment server
The source code repository is where your project’s source code is stored. The build server is responsible for compiling the source code and running the tests. The test server is used for running the unit tests and other tests. The deployment server is used for deploying the application to the production environment.
Now that we know what a CI CD pipeline is, let’s take a look at how to set up a CI CD pipeline in Jenkins.
First, you will need to install Jenkins on your build server. Jenkins is available as a free download from https://jenkins.io/.
Once Jenkins is installed, you will need to create a Jenkins project. To create a Jenkins project, click on the New Item link in the Jenkins dashboard.
In the New Item dialog, select the Freestyle project type and click on the Next button.
In the Project Name field, enter the name of your project and click on the Next button.
In the Source Code Management section, select the Git option and click on the Next button.
In the Git Repository URL field, enter the URL of your Git repository and click on the Next button.
In the Build Triggers section, select the Continuous Integration option and click on the Next button.
In the Build Environment section, select the Use Jenkins build environment option and click on the Next button.
In the Build section, select the Use Groovy script option and click on the Next button.
In the Test section, select the Use Groovy script option and click on the Next button.
In the Post-build Actions section, select the Deploy to production environment option and click on the Next button.
Click on the Finish button to create the Jenkins project.
Now that you have created a Jenkins project, you will need to add a build script to the project. To add a build script, click on the New Item link in the Jenkins dashboard and select the Groovy script option.
In the Groovy script file field, enter the name of your build script and click on the Save button.
Now, you will need to add your project’s source code to the Git repository. To add your project’s source code to the Git repository, open a terminal window and cd to the root of your project’s source code.
Then, run the following command:
git init
git add .
git commit -m ‘initial commit’
git remote add origin https://github.com/username/reponame.git
git push origin master
Once your project’s source code is in the Git repository, you can build and test your project by running the following command:
git checkout -b testing
./gradlew build
./gradlew test
git checkout -b production
./gradlew deploy
Conclusion
In this article, we have explained how to set up a CI CD pipeline in Jenkins. We have also shown how to add a build script to a Jenkins project and how to add your project’s source code to a Git repository.
How do I start CI CD pipeline in Jenkins?
CI/CD pipelines help to automate the software development process by integrating testing and deployment tools into a single workflow. Jenkins is a popular open-source tool used to create and manage CI/CD pipelines. In this article, we will show you how to create a simple Jenkins pipeline that can be used to build and deploy a Java application.
First, we will create a Jenkins project and configure it to build our Java application. We will then create a Jenkins pipeline that will build and deploy our application. Finally, we will add some additional steps to our pipeline to improve the quality of our application.
Creating a Jenkins Project
The first step is to create a Jenkins project. We can do this by clicking on the New Item button in the Jenkins menu.
We will then give our project a name and select the Freestyle project type.
Next, we will need to configure our project to build our Java application. We can do this by adding a build step that will execute the Maven build command.
We will also need to add a Jenkinsfile to our project. The Jenkinsfile contains the pipeline code that will be used to build and deploy our application.
The Jenkinsfile contains a number of Groovy statements that will be executed by Jenkins. We will not go into detail on the syntax of the Jenkinsfile in this article, but we will show you an example of how to use the Jenkinsfile to build and deploy a Java application.
Building and Deploying a Java Application
The Jenkinsfile contains a number of Groovy statements that will be executed by Jenkins. We will not go into detail on the syntax of the Jenkinsfile in this article, but we will show you an example of how to use the Jenkinsfile to build and deploy a Java application.
The Jenkinsfile contains the following code:
def applicationName = ‘myApplication’
def deployDir = ‘deploy/’ + applicationName
def buildCommand = ‘mvn clean install’
def deployCommand = ‘mvn package -DskipTests -Pprod -Ddeploy.skip=false’
def stage = ‘build’
def job = ‘myJob’
def pipeline = {
stage(‘build’) {
job(applicationName: applicationName, stage: stage) {
buildCommand
}
}
stage(‘deploy’) {
job(applicationName: applicationName, stage: stage) {
deployCommand
}
}
}
In this code, we have defined the following variables:
applicationName: The name of our Java application.
deployDir: The directory where our application will be deployed.
buildCommand: The Maven build command that will be executed by Jenkins.
deployCommand: The Maven deploy command that will be executed by Jenkins.
stage: The stage of the Jenkins pipeline.
job: The Jenkins job that will be executed by the pipeline.
pipeline: The Jenkins pipeline.
The Jenkinsfile will be executed in the following order:
The Jenkinsfile will be executed in the following order:
1. The Jenkinsfile is read and executed.
2. The buildCommand is executed.
3. The deployCommand is executed.
4. The stage is changed to ‘deploy’.
5. The job is executed.
6. The stage is changed to ‘build’.
7. The job is executed.

What are the 3 types of pipelines in Jenkins?
There are three types of pipelines in Jenkins: Declarative, Scripted, and Manual.
Declarative pipelines are the simplest type of pipeline and are defined using a Jenkinsfile that describes the pipeline’s structure in a simple, YAML-based syntax. Scripted pipelines are more complex and allow you to use a variety of languages, including Groovy, to create more sophisticated pipelines. Manual pipelines are the most complex type and allow you to execute pipelines manually, rather than through Jenkins.
How do you implement CI CD pipeline?
CI CD pipeline is a software development term that stands for “continuous integration” and “continuous delivery”. It describes a process of software development where changes are made to the code base and tested frequently, with the goal of getting changes into production quickly and safely.
There are a number of different tools and technologies that can be used to implement a CI CD pipeline. In general, the process involves setting up a system that can:
1. Automatically build the software every time a change is made to the code base.
2. Automatically run tests on the software every time it is built.
3. Automatically deploy the software to a test or production environment when it is ready.
There are a number of different tools and technologies that can be used to achieve these goals. Here are a few of the most popular options:
1. Jenkins: Jenkins is a popular open-source tool that can be used to automate the build and testing process. It can be used to build software from a variety of different sources, including Git repositories, Subversion repositories, and Maven repositories.
2. Selenium: Selenium is a popular open-source tool that can be used to automate the testing of web applications. It can be used to test the functionality of web applications and to verify that they meet the business requirements.
3. Puppet: Puppet is a popular open-source tool that can be used to automate the deployment of software. It can be used to deploy software to servers in a test or production environment.

How do I write Jenkins pipeline code?
In order to write Jenkins pipeline code, you’ll need to understand the basics of Jenkinsfile syntax.
The Jenkinsfile syntax is based on the Groovy programming language. Groovy is a small, simple, and powerful programming language that is well-suited for writing Jenkins pipeline code.
If you’re not familiar with Groovy, don’t worry. The basics of Groovy are relatively easy to learn. And, as you become more familiar with Jenkins pipeline code, you’ll find that Groovy is a very versatile language that can help you to write efficient and concise Jenkins pipeline code.
In general, the Jenkinsfile syntax is very simple. A Jenkinsfile is a text file that contains a list of Jenkins pipeline steps. Each step is a Groovy script that performs a specific task.
The basic syntax of a Jenkins pipeline step is as follows:
def stepName = ‘step description’
def env = ‘environment name’
def script = ‘script to run’
def parameters = ‘parameters to pass to the script’
def publisher = ‘publisher to use’
The stepName is the name of the Jenkins pipeline step. The env is the name of the environment in which the step should run. The script is the Groovy script that should be run as part of the step. The parameters are the parameters that should be passed to the script. The publisher is the publisher that should be used to run the script.
Here is an example of a Jenkins pipeline step:
def stepName = ‘echo message’
def env = ‘test’
def script = ‘println(“Hello world!”)’
def parameters = ”
def publisher = ‘shell’
The stepName is ‘echo message’. The env is ‘test’. The script is ‘println(“Hello world!”)’. The parameters are empty. The publisher is ‘shell’.
When you run a Jenkins pipeline, the Jenkins pipeline engine will execute the steps in the order that they are listed in the Jenkinsfile.
Each step will be run in its own isolated environment. This means that the scripts and parameters in one step will not affect the scripts and parameters in any other steps.
The Jenkins pipeline engine will also take care of ensuring that the correct publisher is used to run each script. This means that you don’t have to worry about specifying the correct publisher for each step.
Now that you understand the basics of Jenkinsfile syntax, let’s take a look at a few examples of Jenkins pipeline code.
The following example shows a simple Jenkins pipeline that prints the message ‘Hello world!’ to the console:
def stepName = ‘echo message’
def env = ‘test’
def script = ‘println(“Hello world!”)’
def parameters = ”
def publisher = ‘shell’
This Jenkins pipeline will print the following message to the console:
Hello world!
The following example shows a Jenkins pipeline that downloads a file from a URL and prints the contents of the file to the console:
def stepName = ‘download file’
def env = ‘test’
def script = ‘url = “https://www.jenkins-ci.org/sites/default/files/jenkins-logo.png”
def file = new File(“${env.WORKSPACE}/jenkins-logo.png”)
downloadFile(url, file)’
def parameters = ”
def publisher = ‘shell’
This Jenkins pipeline will download the
