前言

千辛万苦，连哄带骗，向领导申请了 3 台 Mac 二手机器，来搞 IOS 自动化。安装单独执行都没问题，集成起来问题来了。有两台机器的 WDA 端口一直监听在 8100 上，集成多开无法搞定！

尝试

机器上修改 WDA 源码，设置固定端口 8200，编译后，WDA 确实可以监听 8200，但是我 java 里如下设置后，appium 启动后 WDA 依然还是会自动编译。
capabilities.setCapability("useNewWDA", false);//不重新装 WDA
capabilities.setCapability("wdaLocalPort", 8200);//监听 8200
各位有没有办法 让 WDA 不编译或者指定端口啊

设置参数 USE_PORT

Build settings from command line:
    USE_PORT = 8300

可以看到 设置 8300 时，编译后 端口仍然是 8200，脑壳疼，各位有么有解决方案啊。先拜谢各位了！
