I have the following DSL structure:

freeStyleJob { wrappers { credentialsBinding { [ $class:"AmazonWebServicesCredentialsBinding", accessKeyVariable: "AWS_ACCESS_KEY_ID", credentialsId: "your-credential-id", secretKeyVariable: "AWS_SECRET_ACCESS_KEY" ] } } steps { // ACCESS AWS ENVIRONMENT VARIABLES HERE! } }

However, this does not work. What is the correct syntax to do so? For Jenkins pipelines, you can do:

withCredentials([[ $class: "AmazonWebServicesCredentialsBinding", accessKeyVariable: "AWS_ACCESS_KEY_ID", credentialsId: "your-credential-id", secretKeyVariable: "AWS_SECRET_ACCESS_KEY"]]) { // ACCESS AWS ENVIRONMENT VARIABLES HERE! }

but this syntax does not work in normal DSL job groovy.

tl;dr how can I export AWS credentials defined by the AmazonWebServicesCredentialsBinding plugin into environment variables in Groovy job DSL? (NOT PIPELINE PLUGIN SYNTAX!)
