该类主要是为了提供IBuildInfo信息的。所以目光转到IBuildInfo接口中：

该接口中定义了一些方法都是跟属性相关的，其实现在BuildInfo中。

提供的属性有build的id号，build的目标名称，测试标签，根目录，build的分支，测试类型。关机要理解build是什么意思，我还不是太了解build这个意义，暂时先用build来代替吧，等我了解了，再做解释。在原生的cts中，使用的是CtsBuildProvider，很简单的就是把cts的根目录属性设置上，然后是buildId，测试目标，build命令设置好就返回了。但是你如果要添加你自己的实现类，肯定不是简单的这么一点代码。比如你要做的测试时测试你的系统，那么这里面提供的东西就多了。首先你的系统存放的地址，分支号，要build的版本号等等都要在这里面获取并存到buildinfo对象中返回给TestInvocation中。
