After Jenkins upgrade to 2.249, the "password" parameter can't be used since the defaultValue("foo") has been replaced by defaultValueAsSecret(Secret.fromString("foo")) (as described in https://issues.jenkins.io/browse/JENKINS-63499) and DSL Job plugin doesn't recognize the  hudson.util.Secret class.

Getting the error:

No such property: Secret for class: javaposse.jobdsl.plugin.structs.DescribableContext

Example:

password{
   name('name')
   description('description')
   defaultValueAsSecret(Secret.fromString("foo"))
}
