Suppose you want to inject a credential into a Pipeline script. The cloudbees note does not include Pipeline script examples. https://support.cloudbees.com/hc/en-us/articles/203802500-Injecting-Secrets-into-Jenkins-Build-Jobs
The Jenkins Pipeline Docs' description of the git pushmethod doesn't have an example using injected credentials.
(https://jenkins.io/doc/pipeline/examples/#push-git-repo)
The Snippet generator is helpful, but not not if you try to follow the instructions at: https://wiki.jenkins-ci.org/display/JENKINS/Credentials+Binding+Plugin
