Develop jenkins groovy script in Eclipse

Is it possible to develop a groovy script (pipeline) for Jenkins in Eclipse? I want to connect to a running Jenkins instance and create / start some jobs. How can i achieve this?

To work with Jenkins Pipeline, I have setup Eclipse like this:

  1. Download and extract Jenkins.war Distribution (it's just a zip file with *.war file extension) from jenkins.io, currently version 2.361.1 LTS.

  2. Run the jenkins war file.

    • 2.1. Open a terminal and run java -jar jenkins.war.You will see that Jenkins will ask for the initial configuration and it will provide an initial password.

    • 2.2. Copy the initial password showed in the terminal.

    • 2.3 Open http://localhost:8080 in a WebBrowser and paste the initial password you have copied from the terminal.

    • 2.4. Follow the steps to install the default plugins. All of these files will be saved in $HOME/.jenkins folder.

  3. Install Eclipse Java IDE Version 2022-03 (4.23.0), I chose flavor: "Eclipse IDE for Java Developers"

  4. Install Eclipse Groovy Plugin 4.5.0 (via Help->Marketplace search for groovy)

  5. Create an Eclipse User Library via Window -> Preferences:

    Then go to Java -> Build Path -> User Libraries, add new User Library with name "Jenkins Pipeline". Then add the following "External Jars..." to this library.

    Uncompress jenkins.war (tar xvf jenkins.war) file and add the following files:

    • 5.1. jenkins/WEB-INF/lib/*.jar Add these libraries from the plugins directory of jenkins home:

    • 5.2. ~/.jenkins/plugins/workflow-cps-global-lib/WEB-INF/lib/*.jar

      If you cannot find this directory it means you are running a new version of Jenkins. In this case, you should use: ~/.jenkins/plugins/pipeline-groovy-lib/WEB-INF/lib/*.jar

    • 5.3. ~/.jenkins/plugins/workflow-cps/WEB-INF/lib/*.jar

    • 5.4. I also add junit to the library because it is often used:

      ~/.jenkins/plugins/junit/WEB-INF/lib/*.jar

  6. Create your groovy pipeline project:

    File -> New -> Project... -> Groovy -> Groovy Project.

    Then add the User Library "Jenkins Pipeline" to the Build Path:

    Right click the groovy project -> Build Path -> Add Libraries -> User Library

  7. Finally add more libraries from the plugins folder to your project according to your needs

Jenkins does not have strong IDE support in any IDE. However, Eclipse (as well as most major java IDE's) does have a groovy plugin and you can import the core jenkins jars to get some auto-completion. At the very least, the IDE gives you autoformatting, with is of some help. Once you've developed your script, you will have to copy it out to jenkins to test.
