Groovy is supported in Jenkinsfile for quick scripting.However, lots of features in the Groovy language is not supported and simple works in Groovy can be really tricky in Jenkinsfile.
Pipeline is groovy based script that have set of plug-ins integrated for automating the builds, deployment and test execution. Pipeline defines your entire build process, which typically includes stages for building an application, testing it and then delivering it. The Jenkinsfile already had a basic declarative pipeline defined. Jenkins configuration. There are configuration steps that need to be done in Jenkins before we can run the scans. First, you need to install the SonarQube Scanner plugin in Jenkins. Configure the plugin in the 'Configure System' Jenkins section. You need to set the URL of the.

Since Pipeline code (i.e. Scripted Pipeline in particular) is written in Groovy-like syntax, if your IDE is not correctly syntax highlighting your Jenkinsfile, try inserting the line #!/usr/bin/env groovy at the top of the Jenkinsfile, footnotegroovyshebang:Shebang line (Groovy syntax) which may rectify the issue.

Groovy Script Jenkins
In summary, if it is possible, use another script language (e.g., Python) for file manipulation in Jenkinsfile.It is time consuming to navigate all tricky stuffs of Groovy implementaiton in Jenkins:
- In-process Script Approval: you have to approve every single class and method one by one.
- Some features of Groovy is not supported and it takes time to figure out what is not supported and how to work around. When in doubt, use
@NonCPS
.
Groovy method in Jenkinsfile
Some notes:
import
statements must be at the top, right after the shebang and before anything else.- The Groovy methods must be annotated with
@NonCPS
or Jenkins will report the error 'java.io.NotSerializableException'. - The Groovy methods can not be defined inside a
step
block. It must be defined at the top. @NonCPS
is required since the Groovy method uses several non-serializble objects.
Groovy method in separate script
Groovy method in shared library
The above Nexus authentication code is likely repeated across multiple Maven builds.Therefore, it is worth converting it into a DSL into a Shared Library in Jenkins.The DSL takes two parameters:
- templateFile: settings.xml template with Nexus credentials info redacted.
- command: Maven command with settings file NOT specified (i.e., NO '-s' option in the command).
The example usage is as follows:
The Jenksinfile is much cleaner since most of implementation details have been moved inside the DSL:
The Pipeline Plugin for theJenkins Continuous Integration system enables you todefine jobs in code, and store them as files within your source coderepositories. Version 2 of Jenkins includes Pipeline as standard, and it is easyto add Docker support.
Free version of omnisphere. Jenkins uses the Groovy scripting language fordefining jobs with Pipeline, but you can write scripts without learning thedetails of Groovy. Your job code can call functions from any Jenkins plugin that supports Pipeline.
Jenkins Pipeline Load Groovy Script
In most cases, you put the script in a file (calledJenkinsfile by default), and add this to the version control repository foryour project. This means that each job only need a minimal configuration on theJenkins server, which specifies the Jenkinsfile.

You can also write Pipeline scripts directly into the Web interface of Jenkins, butshould only use this feature for development and testing.
To integrate Docker with Pipeline, install Docker on the Jenkins server and addthe CloudBees Docker PipelinePluginto the Jenkins installation. Check the compatibilitylistfor the status of other plugins. You do have to ensure that all of the pluginsthat you reference are installed on every Jenkins instance that you use for thatjob.
If you maintain Jenkins version 1 systems you will need to install the Pipeline Pluginthrough the usual process. It is automatically included in all new installationsof Jenkins 2.
Create a file in the version control repository for your project. Set the nameof the file as Jenkinsfile unless you need to have multiple buildscripts in your repository.
Each file defines a node, which represents the instance on which the stepswill run. Within the node, write a series of steps. You define a step likethis:
You automatically have access to the features of the Groovy scripting language, and the built-in env object gives you access to environment variables.Jenkins plugins provide extra objects that you may use within the script, suchas docker. Avoid putting complex commands directly in your Jenkins scripts,though. Write any commands that require multiple options or other logic asseparate scripts in an appropriate language, such as UNIX shell or PowerShell,and call them from your Jenkins build script.
The docker object enables you to run containers from images in Dockerrepositories, and execute commands within the containers. To run steps inside acontainer, rather than the host system, declare the steps within an inside() {}block. If you specify an image name for a container without a repositoryaddress, the image is downloaded from the Docker Hub.
The contents of the workspace are automatically shared with the container. Thismeans that commands will run as you would expect, and post-build steps likearchive will work correctly without any changes.
For example, this snippet starts a container from the ruby image tagged2.3.1 and runs two steps that execute shell commands within the container:
You may use multiple containers in a single Jenkins job.
Jenkins 2 includes the Credentials Binding Plugin, so that you can access stored credentials within your Pipeline scripts.
Create a withCredentials() {} block to retrieve a credential and make it available as an environment variable within the block:
Fifa 14 mod fifa 19 ppsspp. Here is a longer example script:
First, define the credentials for the Jenkins CI server to access your sourcecontrol system in the Web interface using Manage Jenkins > Credentials. Forexample, an SSH key for access to Git repositories.
Create a new job in the Jenkins Web interface, selecting the Pipeline type. Inthe Pipeline section of the job settings, set the Definition to Pipelinescript from SCM, the SCM to Git, then enter the Repository URL andspecify the set of Credentials. You do not need to add any other settings.

The tutorial for Pipeline explains how to install and use it. Similarly, the Docker Pipeline Plugin is well-documented.
