Jenkins pipelines from SCM in different branch not working

Question

I'm working with pipelines in Jenkins in a environment which already has configured a pipeline script from SCM which then uses a groovy file for the stages/jobs inside the pipeline. This scripts are on Bitbucket in a master branch.

Every time jenkins jobs starts it call master branch and it runs with no problem and the stages of the pipeline are run.

Now I created a new branch on bitbucket and modified the groovy file to include some more steps (like running unit tests and some more stuff) and I would like that jenkins runs that script but with the branch I specified (the one I created).

Thing is that eventhough I specified my branch in in "branch specifier", jenkins still runs the master branch. Here are some images of what I have configured.
How can I specify the branch I want to be run on the pipeline script from SCM?

This is the groovy file, but groovy files does steps of the code that will be deployed. It doesn't run any jenkin script. Where it says "master" is of maser code to be deploy and not the deploy script.

Groovy file:

def call(body) {

    def config = [:]
    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = config
    body()

    def artifactName = 'imp'
    def artifactExt = '.war'
    def artifactVersion = '0.0.1'

    def buildPath = 'target/'
    def warFile = artifactName + '-' + artifactVersion + artifactExt
    def warPath = buildPath + warFile
    def warNoVersion = artifactName + artifactExt

    def deployPath = '/var/lib/tomcat8/webapps/'
    def deployFile = deployPath + warNoVersion

    node {
        // Clean workspace before doing anything
        //deleteDir()

        try {

            stage ('Code Checkout') {
                git branch: 'master',
                    credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
                    url: 'ssh://[email protected]/xxxxx/xxxximporter'

everything looks fine...have you verified the commit id in the console output ?...can you share the console output by hiding the confidential information.. — Here_2_learn
there I edited it and add that. 3 branches are seen, but master is run. I want that job run my branch "DEVOPS-568-pipeline-ci" — Chanafot
I include the part where starts running the master branch job. then job run successfully an pipeline ends ok but only wit master branch — Chanafot
can you share the pipeline script where the "checkout scm" is happening ? — Here_2_learn
the script only contains this: @Library("gp-extractor-deploy") _ DeployExtractor { confiFileId = "extractor-conf.properties" serverIp = 'x.x.x.x' slackChannel = '#xxxxx' } which call a groovy file in which all jobs/steps are run — Chanafot

The issue is even though the Jenkinsfile is from the required branch, code checkout is happening through "master" branch. The reason is code checkout is from branch "master" in "code checkout stage". Change the code as follows:

try {
    stage ('Code Checkout') {
        git branch: 'REQUIRED BRANCH',
            credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
            url: 'ssh://[email protected]/xxxxx/xxxximporter'

An alternative and rather better option is to provide GIT BRANCH as parameter from the Jenkins job. Snapshot below.

UPDATE: This can be achieved by installing the git parameter plugin.

and add the following code snippet in your "code checkout" stage and change accordingly. Here "gitbranch" is the parameter that you are passing from build.

 checkout changelog: false, poll: false, scm: [$class: 'GitSCM', branches: [[name: gitbranch]], doGenerateSubmoduleConfigurations: false,    
extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '********', url: '**********']]]
