Jenkins: Trigger another job with branch name - jenkins

Question

I am using Jenkins Pipeline via declarative and I would like to trigger another job with branch name.
For instance, I have two different pipeline(PipelineA -PipelineB) with stages JobA and JobB.
One of the stage for JobA should trigger the JobB via paramater using env.GIT_BRANCH. What I mean, if we trigger the JobA via origin/develop, then it should trigger the 'JobB' and run the stages where it has origin/develop condition.
Meanwhile, we also making some separate changes on JobB and it also has its own GIT_BRANCH expression.Thus I could not able to find a way to manage this separately without affecting JobA. To be clarify, when JobA trigger JobB with origin/stage parameter, due to latest changes on JobB is origin/development whereas GIT_BRANCH is origin/development, I can not able to run the stages which has stage condition.
Here is my script.
stage ('Job A') {
steps {
script {
echo "Triggering job for branch ${env.GIT_BRANCH}"
ret = build(job: "selenium_tests",
parameters: [
string(name: "projectName", value: "Project1"),
string(name: "branchName", value: "env.GIT_BRANCH")
],
propagate: true,
wait: true)
echo ret.result
currentBuild.result = ret.result
}
}
}
parameters {
string(defaultValue: "project1", description: 'Which project do you want to test?', name: 'projectName')
string(defaultValue: "origin/development", description: 'Environment for selenium tests', name:'branchName')
}
stage ('Job B') {
when {
beforeAgent true
expression { params.projectName == 'Project1' }
expression { params.branchName == "origin/stage"}
expression{ return env.GIT_BRANCH == "origin/stage"}
}
steps {
script {
//Do something
}
}
}

Pass down one more param for branch when trigger Job B
stage('Trigger Job A') {}
stage('Trigger Job B') {
when {
allOf {
beforeAgent true
expression { params.projectName == 'Project1' }
expression{ return env.GIT_BRANCH == "origin/stage"}
}
}
steps {
build(job: "selenium_tests/Job B",
parameters: [
string(name: "projectName", value: "Project1")
strint(name: "branchName", value: "${env.GIT_BRANCH}")
],
propagate: true,
wait: true)
}
}
In Job B' Jenkinsfile add one stage as the first stage to switch to desired branch
pipeline {
parameters {
string(name: 'branchName', defaultValue: 'develop')
}
stages {
stage('Switch branch') {
steps {
sh "git checkout ${params.branchName}"
}
}
// other stages
}
}
