How do you use variables in Jenkins pipeline?
Variables in a Jenkinsfile can be defined by using the def keyword. Such variables should be defined before the pipeline block starts. When variable is defined, it can be called from the Jenkins declarative pipeline using ${…} syntax.
How does Jenkins Multibranch pipeline work?
The Multibranch Pipeline project type enables you to implement different Jenkinsfiles for different branches of the same project. In a Multibranch Pipeline project, Jenkins automatically discovers, manages and executes Pipelines for branches which contain a Jenkinsfile in source control.
How do I get Jenkins environment variables?

When to add job url in multibranch pipeline?
To fully support multibranch pipelines, the job/ {BRANCH} post-fix will need to be appended the job url before the build section. After a quick pass over the code, I believe this won’t be too difficult for the regular triggers. It may require a bit more finessing for manual triggers.
How to inject environment variables in Jenkins pipeline?
Back to your Jenkinsfile, you can use configFileProvider to save this configuration as a groovy file in your workspace. Once it’s available, you can load this file using load. This essentially executes the groovy file, thus injecting the environment variables defined in the file.
