make framework # Android11开始，建议使用命令：make framework-minus-apex
编译成功后，framework.jar会生成到：out/target/product/产品代号/system/framework中。
make services
编译/frameworks/base/services目录下的代码，详见/frameworks/base/services/Android.bp中的定义

}其中的services.core就包含了/frameworks/base/services/core目录下的内容，例如ActivityManagerService
产物services.jar和framework.jar一样，在/system/framework/目录下，所以调试AMS的时候，make framework是不行的。虽然这样会校验/frameworks/base/services/core目录下的语法错误，但是不会编译services.jar
