How to use groovy variable in jenkins sh command

I am trying to use a groovy variable in my Jenkins file as shown below

def since='2018-06-01';
count = sh(returnStdout: true, script: 'git rev-list --all --count master --since="${since}"').trim();

The variable since is not evaluating in the Jenkins output.

+ git rev-list --all --count master --since=
[Pipeline] echo

Looks like I am doing something wrong in the syntax. Can some one help on this.

If you want to interpolate Groovy variable into the string you have to use double quotes instead (single quotes create String, while double quotes create GString):

count = sh(returnStdout: true, script: "git rev-list --all --count master --since=\\\"${since}\\\"").trim();

Also, if you want to pass --since="2018-06-01" you will have to escape " and \ like in the above example.

Updated code produces following git command:

+ git rev-list --all --count master --since="2018-06-01"
