Can we use a single jenkins file for multibranch piepeline in jenkins using shared libraries?

Question

I am trying to write a jenkinsfile which will take the data from shared libraries in jenkins for multibranch pipeline, something like below:-

@Library('Template')_

if (env.BRANCH_NAME == 'master') {
    jenkins1(PROJECTNAME: 'test', GITURL: 'http://test/test.git')
    } else {
        jenkins2(PROJECTNAME: 'test1', GITURL: 'http:////test/test.git')
    }

so the pipeline take the shared library depending upon the if condition, if the branch is master if statement data should work or else should be build.

Yes that’s possible. Actually we’re using a multibranch project to test our changes to our shared library that way.

You have to use the library step to load the library instead of the @Library annotation, like:

if (condition) {
    library(‘someLib@${env.BRANCH_NAME}’)
} else {
    library(‘someOtherLib’)
}

See https://jenkins.io/doc/pipeline/steps/workflow-cps-global-lib/#library-load-a-shared-library-on-the-fly for all details.
