How to set variables in a multi-line shell script within Jenkins Groovy?

问题:

Suppose I have a Groovy script in Jenkins that contains a multi-line shell script. How can I set and use a variable within that script? The normal way produces an error:

sh """     foo='bar'     echo $foo """

Caught: groovy.lang.MissingPropertyException: No such property: foo for class: groovy.lang.Binding

回答1:

You need to change to triple single quotes ''' or escape the dollar \$

Then you'll skip the groovy templating which is what's giving you this issue

回答2:

I'm just putting a '\' on the end of line

sh script: """\   foo='bar' \   echo $foo \ """, returnStdout: true

This statement works on my script.
