如何在Jenkins Groovy DSL中获得动态属性

Question

请阅读评论以了解问题。

job(buildV2PerfTest) {
    displayName('Performance Test')
    steps {

        //I am loading a value into a properties file using the shell command. The name of the variable is callbackUrl
        shell('echo "callbackUrl=http://`curl http://169.254.169.254/latest/meta-data/public-hostname`:8080" > env.properties')

        //then I add the propeties file to Jenkins properties
        environmentVariables {
            propertiesFile('env.properties')
        }
        maven {
            goals('-P performance test')
            //I want to pass to maven a loaded property here
            property('callbackUrl', "${callbackUrl}")
        }
    }
}

问题在于，当我编译此代码时，它表示该属性不存在。确实。当我触发工作时它会存在。我想知道如何引用动态属性。

P.S。 documentation告诉如何加载变量，但未解释如何访问它们

解决方案是：

property('callbackUrl', "\$callbackUrl")
