有两种传参方式，-DdeviceType=android，-P DEV，相应的默认值的设置也有两种方式，个人实际工作中倾向于第一种：

1
mvn test -DdeviceType=android -P DEV --settings /Users/tracenote/.m2/setting.xml

输出：

========= deviceType: android
========= environment: DEV environment

不传参数，程序输出默认值：

1
mvn test   --settings /Users/tracenote/.m2/setting.xml

输出：

========= deviceType: iOS
========= environment: QA environment
