groovy环境中的flyway gradle插件

我正在尝试自定义gradle以从groovy文件中获取flyway属性

我的environment.groovy文件

environments {
    dev {
        flywayProperties {
            driver="oracle.jdbc.driver.OracleDriver"
            url="jdbc:oracle:thin:@localhost:1521/XE"
            user="test"
            password="test"
            locations= "classpath:db/migration,db/insert"   
        }
    }

    qa {
        flywayProperties {
            driver = "oracle.jdbc.driver.OracleDriver"
            url = "jdbc:oracle:thin:@localhost:1521/XE"
            user = "test"
            password = "test"
            locations = "classpath:db/migration"
        }
    }
}

和我的build.gradle

loadConfiguration()

task printProps << {
    println "Driver:  $config.flywayProperties.driver"
    println "URL:  $config.flywayProperties.url"
    println "User:  $config.flywayProperties.user"
    println "Password:  $config.flywayProperties.password"
    println "Locations:  $config.flywayProperties.locations"
}

def loadConfiguration() {
    def environment = hasProperty('env') ? env : 'dev'
    project.ext.envrionment = environment
    println "Environment is set to $environment"

    def configFile = file('environment.groovy')
    println configFile.toURL()

    def config = new ConfigSlurper("$environment").parse(configFile.toURL())
    project.ext.config = config
}

flyway {
    driver = "$config.flywayProperties.driver"
    url = "${config.flywayProperties.url}"
    user = "${config.flywayProperties.user}"
    password = "${config.flywayProperties.password}"
    //locations = ['classpath:db/migration' , 'db/insert']   -- Works fine
    locations = "${config.flywayProperties.locations}" -- Throws below error
}

尝试执行“ gradle flywayInfo”时出现以下错误

**失败：构建失败，并出现异常。*出了什么问题：任务'：flywayInfo'的执行失败。

执行flywayInfo位置未知前缀时发生错误（应该是文件系统：或类路径：）：：**

有人可以帮助我如何提供位置。因为我需要根据环境提供多个位置

谢谢
