来自groovy.config的groovy打印环境(groovy print environments from groovy.config)

 如何从配置文件中打印可用的环境？ ojbect ConfigSlurper创建什么形式？ 
 
 我试过了 
 
def config2 = new ConfigSlurper().parse(new File('obieeadmincfg.groovy').toURL())

config2.config.environments.each { println ${it} }
        and 
println prettyPrint(toJson(config2))
        and
for ( i in 0 ..config2.config.environments.size()-1)
    println config2.config.environments[i]
 
 groovy.config 
 
//Config3.groovy
obieadmin {
    //default values
    serverurl = "http://default.mycompany.com"

}

environments {
    pldev01 {
        obieeadmin {
            serverurl = 'devgdwobi03.x.com'

        }
    }
    plsbx02 {
        obieeadmin {
            serverurl = 'devgdwobi03.x.com'

        }
    }
}

how do I print available environments from a config file? What is the form of the ojbect ConfigSlurper creates?
 
I tried 
 
def config2 = new ConfigSlurper().parse(new File('obieeadmincfg.groovy').toURL())

config2.config.environments.each { println ${it} }
        and 
println prettyPrint(toJson(config2))
        and
for ( i in 0 ..config2.config.environments.size()-1)
    println config2.config.environments[i]
 
groovy.config
 
//Config3.groovy
obieadmin {
    //default values
    serverurl = "http://default.mycompany.com"

}

environments {
    pldev01 {
        obieeadmin {
            serverurl = 'devgdwobi03.x.com'

        }
    }
    plsbx02 {
        obieeadmin {
            serverurl = 'devgdwobi03.x.com'

        }
    }
}
