Expand parameter variable in withMaven

Can you use a variable in the withMaven command in pipeline. Example below:

withMaven(jdk: ‘jdk1.8.0_391’,
maven: ‘Maven_3.8.6’,
mavenLocalRepo: “blah”) {
blah blah blah
}

What I’d like is something like:
withMaven(jdk: ‘jdk1.8.0_$JDK_VERSION’

But that and ${env_JDK_VERSION} don’t seem to expand the JDK_VERSION parameter I am setting. I am sure I am missing something obvious, but hoping to be able to choose different JDK versions as a parameter and not have to change the withMaven syntax to accompany it.

try with double quotes:
withMaven(jdk: "jdk1.8.0_${JDK_VERSION}", ...

LOL, well that’s embarrassing. Of course that fixed it. Thanks for my head palm moment of the day.
