Jenkins Global environment variables in Jenkinsfile

Question

How do I invoke Global environment variables in Jenkinsfile?
For example, if I have a variable -

 name:credentialsId 
 value:xxxx-xxxx-xxxxx-xxxxxxxxx
         


        

Answer 1

Another syntax is $ENV:xxxx

node {
echo "Running $ENV.BUILD_ID on $ENV.JENKINS_URL" }

This worked for me
