How to use an environment variable in a environment variable in a Jenkinsfile?

Question

I would like to have a environment variable COMPOSE_PROJECT_NAME with the value denpal-4 for a Jenkins job with build_id 4.

environment { COMPOSE_PROJECT_NAME = 'denpal-$(BUILD_ID)' }

The alternative would be writing this in every sh-block

sh ''' export COMPOSE_PROJECT_NAME = 'denpal-$(BUILD_ID)' code... '''

This would go against the DRY (Don't repeat yourself) principle however. Is something in environment {} possible?

UPDATE/ANSWER: double quotes instead of single quotes fixed it.

Yes, you can assign the value to variable in environment stage (using env as a prefix to the variable) and then can use it in any stage, please see below:-

environment { env.COMPOSE_PROJECT_NAME = "denpal-${BUILD_ID}" }
