Jenkins MultiBranch Pipeline: Select to build only 2 specific branches - jenkins

Question

I have a Jenkins MultiBranch project and I want the test circle to run only on two specific branches on master and on dev. I tried to add on all stages the following
when { anyOf { branch 'master'; branch 'dev' } }
but the only thing I managed to achieve was to deactivate all branch runs
Here is my full pipeline Jenkinsfile
pipeline {
agent any
triggers {
cron('H 0 * * *')
}
options {
disableConcurrentBuilds()
}
stages {
stage('Prepare env') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
sh 'rm -rf venv'
sh 'rm -rf "${WORKSPACE}/uploads"'
sh 'rm -rf "${WORKSPACE}/downloads"'
sh 'mkdir "${WORKSPACE}/uploads"'
sh 'mkdir "${WORKSPACE}/downloads"'
catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE')
{
sh 'docker kill $(docker ps -q)'
sh 'docker rm $(docker ps -a -q)'
sh 'docker volume rm $(docker volume ls -q)'
}
}
}
stage('Start Services') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
}
}
stage('Test Common') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
}
}
stage('Test Validations') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
}
}
stage('Test CSV Issuance') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
}
}
stage('Test XLS Issuance') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
}
}
stage('Clean env') {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
sh 'rm -rf venv'
sh 'rm -rf "${WORKSPACE}/uploads"'
sh 'rm -rf "${WORKSPACE}/downloads"'
catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE')
{
sh 'docker kill $(docker ps -q)'
sh 'docker rm $(docker ps -a -q)'
sh 'docker volume rm $(docker volume ls -q)'
}
}
}
}

Can you post the full pipeline you have?
You would use the when block on the stage you want run only on the two branches e.g.
pipeline {
agent any
stages
{
stage ("Testing") {
when {
anyOf {
branch 'master'
branch 'dev'
}
}
steps {
echo "run testing"
}
}
stage ("everything") {
steps{
echo "run on all branches"
}
}
}
}
tested pipeline
pipeline {
agent any
stages {
stage("stage") {
when { anyOf { branch 'master'; branch 'dev' } }
steps {
echo "Hello"
}
}
}
}
on master
[Pipeline] stage
[Pipeline] { (stage)
[Pipeline] echo
Hello
[Pipeline] }
[Pipeline] // stage
On Fish
[Pipeline] stage
[Pipeline] { (stage)
Stage "stage" skipped due to when conditional
[Pipeline] }
[Pipeline] // stage
