How to set different environment variables in a Jenkinsfile depending on the Git branch

I want to use different variables based on the Git branch to avoid using separate Jenkinsfiles for different branches. However, it seems that Groovy syntax doesn’t work within the environment{} directive.

I tried something like this without success:

		

			
		

		if (current_branch == 'development') {
    CONFIG = 100
} else if (current_branch == 'main') {
    CONFIG = 200
}

How do you avoid creating multiple Jenkinsfiles?

I usually add a preliminary stage to set environment variables based on the branch:

		

			
		

		stage('Setup') {
    steps {
        script {
            if (env.BRANCH_NAME == 'development') {
                env.CONFIG = '100'
            } else if (env.BRANCH_NAME == 'main') {
                env.CONFIG = '200'
            }
        }
    }
}
