高手解答下，为什么在编译framework源码时报 *** No rule to make target `out/target/product/generic/system/framework/framework-res.apk', needed by `out/target/product/generic/system/framework/framework.jar'.

Answer 1

 “*** No rule to make target”说的是缺少生成目标的规则

Answer 2

是不是单独编译framework是要在已编译全部工程的前提下？我想要单独编译framework，缺乏实战，求讨教
