Jenkins is an open-source automation tool written in Java with plugins built for Continuous Integration purposes. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.

The Jenkins project was originally named Hudson, and was renamed after a dispute with Oracle, which had forked the project and claimed rights to the project name. On February 1, 2011, Oracle said that they intended to continue development of Hudson, and considered Jenkins a fork rather than a rename.

Jenkins is a popular CI orchestration tool. When it comes to test automation, Jenkins provides plugins that help run test suites, gather and dashboard results, and provide details on failures.

As a part of jenkins job, we can run junits, fitnesse, test coverage reports, call shell or bat scripts, etc.

Jenkins is an Automation and CI Tool. It is a java application and very easy to learn. You will learn from a very basic step by step in this course and by the end, you will be able to use Jenkins at all levels.

Jenkins is an open source automation tool written in Java programming language that allows continuous integration. Plugins is used to allow the integration of various DevOps stages. If you want to integrate a particular tool, you have to install the plugins for that tool.

3) What is the requirement for using Jenkins?

• A source code repository which is accessible, for instance, a Git repository.
• A working build script, e.g., a Maven script, checked into the repository.

In today’s world of Agile and DevOps, Jenkins has become an indispensable tool for both Java programmers and DevOps engineers. Jenkins allows you to set up continuous integration (CI) and continuous deployment (CD) pipeline, which reduces risk on Software development and delivery.

A maven is a build tool designed to manage dependencies and the software lifecycle. It is also designed to work with plugins that allow users to add other tasks to the standard compile, test, package, install, deploy tasks. Jenkins is designed for the purpose of implementing Continuous Integration (CI).

For default installation location to C:/Program Files (x86)/Jenkins, a file called initialAdminPassword can be found under C:/Program Files (x86)/Jenkins/secrets. However, If a custom path for Jenkins installation was selected, then you should check that location for initialAdminPassword file.

Here are the reasons why you use should use Jenkins pipeline: Jenkins pipeline is implemented as a code which allows multiple users to edit and execute the pipeline process. Pipelines are robust. So if your server undergoes an unforeseen restart, the pipeline will be automatically resumed.

Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.

Jenkinsfile created by the classic UI is saved directly by Jenkins. The Jenkins file is a base code for Jenkins which executes it as a Groovy script in Jenkins script console.

The main difference between any job and a Pipeline Job is that the Pipeline Scripted job runs on the Jenkins master, using a lightweight executor expected to use very few resources in order to translate the pipeline to atomic commands that execute or send to the agents.

1. Go to the Jenkins build.
2. On the left hand side click the Pipeline steps.
3. Then on the right click on the link that says “Allocate node : Start – (x min in block)”
4. On the the left side click the workspace. Done!

5 Answers. Adding this line to your build script or Jenkinsfile will configure the job to run every night at 11PM. Into the main job configuration of your pipeline (the first), set the “Build periodically” checkbox, and specify the schedule that you want. follow the syntax indications.

To get started quickly with Pipeline:

1. Copy one of the examples below into your repository and name it Jenkinsfile.
2. Click the New Item menu within Jenkins.
3. Provide a name for your new item (e.g. My-Pipeline) and select Multibranch Pipeline.

In a multi-branch pipeline configuration, Jenkins automatically discovers, manages, and executes jobs for multiple source repositories and branches. This eliminates the need for manual job creation and management, as would otherwise be necessary when, for example, a developer adds a new feature to an existing product.

Access Parameters Inside Pipeline Stages You can access a parameter in any stage of a pipeline. Accessing parameters in stages is pretty straightforward. You just have to use params. [NAME] in places where you need to substitute the parameter.

A Jenkinsfile can be written using two types of syntax – Declarative and Scripted. Declarative and Scripted Pipelines are constructed fundamentally differently. Declarative Pipeline is a more recent feature of Jenkins Pipeline which: provides richer syntactical features over Scripted Pipeline syntax, and.

A Jenkinsfile is a text file that contains the definition of a Jenkins Pipeline and is checked into source control. It is assumed that there is already a source control repository set up for the project and a Pipeline has been defined in Jenkins.

Freestyle projects are meant to orchestrate simple jobs for a project. Pipeline Project: The pipeline project is applicable to build pipelines for complex activities that are not suitable for freestyle project. If you want to learn Jenkins, I recommend this Jenkins Certification course by Intellipaat.

Jenkins supports different types of build jobs. Some of them are : Freestyle software project….Share the Knol:

Triggering Jenkins builds by URL

1. Step 1: Setting up a new user. Trigger a build via URL means that the Jenkins endpoint is open to anyone who can hit the server.
2. Step 2: Enable the URL job trigger. Go to the job that you want to trigger and click Configure to edit the job.
3. Step 3: Enable permission for “auto”
4. Step 4: Create the URL.
