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
