configFiles no longer finds maven settings config files?

[Kyle Cronin]

I have the following maven settings config file setup

mavenSettingsConfigFile('central-mirror') {
  content readFileFromWorkspace('maven-settings/central-mirror.xml')
}

and I have a freeStyleJob that is configured to pass this config file to an ant job (which needs the settings file to execute a series of maven jobs). 

freeStyleJob('dsl-template-release') {
 wrappers {
       configFiles {
            file('central-mirror') {
                variable('JENKINS_SETTINGS_FILE')
            }
        }
    }
}

I get the following error when running this above script.

java.lang.NullPointerException: Custom config file with name 'central-mirror' not found
	at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:204)

This worked in previous versions of the plugin, most likely pre 1.30. Any idea how I can get this working again?

I take that part about it working in a previous version. We must have not run the templates job since this configFiles was introduces. I suppose this is now an enhancement request rather than a question :)

I've created a pull request with this enhancement.
