如何在 jenkins 中实现共享库，而不在“管理 Jenkins”中配置“全局管道库”？

Question

Since I don't have access to "Manage Jenkins" menu in my organization, I'm unable to configure my shared library in "Global Pipeline Libraries" in "Manage Jenkins".

Is there any other way to implement this, without configuring in Manage Jenkins?

(or)

Is it possible to configure "Global Pipeline Libraries" part through pipeline script, irrespective of access privileges?

If possible, requesting you to share some code snippets in the answer.

Answer 1

Without configuring in "Manage Jenkins". We can use "LibraryIdentifier" in Pipeline script to load the libraries in the jenkins build.

Answer 2

Load the library

you can load the library from source control (like git) like this:

def myLib= library(
    identifier: 'myLib@master', retriever: modernSCM
    (
        [
            $class: 'GitSCMSource',
            remote: 'https://bitbucket.org/shaybc/commonlib.git',
            credentialsId: 'bitbucketCreds'
        ]
    )
)

Groovy class from the library

assuming this is the groovy class:

package my.domain

class Tester
{
    public static String staticTest()
    {
        return "this is from a static method";
    }

    public String test()
    {
        return "this is from an instance method";
    }
}

Call the methods from scripted pipeline

then you call a static method like this:

myLib.my.domain.Tester.staticTest();

and an instance method like this:

// call the constructor (you can also call a constructor with parameters)
def tester = myLib.my.domain.Tester.new();

// call your instance method
tester.test();

Answer 3

As mentioned in some of the answers above, you can load the library at runtime using library identifier or you can also configure the library at folder level of the Jenkins job that you're trying to run. In most of the cases, the developers don't get admin access to Jenkins. However, they are allowed to access and update configurations at folder level. You can check if you have those privileges. It would be more convenient that loading libraries at runtime for all your pipeline scripts.
