gradle - Gradle 3.4:使用ConfigSlurper构建配置文件

Question

我在build.gradle中有以下任务，并且我尝试根据环境从wsdlURL中获取config.groovy值

loadConfiguration()

task printProps << {
    println "WSDLURL:  $config.wsdlURL"
}

def loadConfiguration() {
    def environment = hasProperty('env') ? env : 'dev'
    System.setProperty('environment', environment)
    println "Environment is set to $environment"

    def configFile = file('config.groovy')
    def config = new ConfigSlurper(environment).parse(configFile.toURI().toURL())
    System.setProperty('config', config) \\line 52
}

以下是我的config.groovy

environments {
    dev {
        wsdlURL = 'https://dev.com/ts/svs.asmx?wsdl'
    }

    qa {
        wsdlURL = 'https://qa.com/ts/svs.asmx?wsdl'        
    }

    stg {
        wsdlURL = 'https://stg.com/ts/svs.asmx?wsdl'        
    }

    prod {
        wsdlURL = 'https://prod.com/ts/svs.asmx?wsdl'
    }
}

当我运行gradle -q -Penv=prod printProps命令时，它失败并显示以下错误

Environment is set to prod

FAILURE: Build failed with an exception.

* Where:
Build file 'build.gradle' line: 52

* What went wrong:
A problem occurred evaluating root project 'SignService'.

Possible solutions: setProperty(java.lang.String, java.lang.String), getProperty

以下是我的环境详细信息

似乎gradle无法将groovy对象设置为系统属性，请问有人可以帮助我修复它吗？

Answer 1

错误消息很清楚

System.setProperty(key, value)需要两个String参数，但是您要传递String和ConfigObject。

也许你想

System.properties['config'] = config

要么

System.properties.put('config', config)
