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

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

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

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

This statement works on my script.
