android-source - 如何正确清理模块并在 AOSP 中重建它？

Question

AOSP 的顶层目录是~/WORKING_DIRECTORY。如果我跑

~/WORKING_DIRECTORY$ make

整个系统构建正确。

根据Building a specific module in the android source code，https://stackoverflow.com/a/30671099/746461，如果我需要重建艺术，我会

cd art
mm

但是它会引发错误：

FAILED: out/target/common/cpplint/art__compiler__optimizing__nodes.h 
/bin/bash -c "(art/tools/cpplint.py --quiet --root=. --filter=-whitespace/line_length,-build/include,-readability/function,-readability/streams,-readability/todo,-runtime/references,-runtime/sizeof,-runtime/threadsafe_fn,-runtime/printf art/compiler/optimizing/nodes.h ) && (mkdir -p out/target/common/cpplint/ ) && (touch out/target/common/cpplint/art__compiler__optimizing__nodes.h )"

如果我留在 ~/WORKING_DIRECTORY 并调用 mm art，它似乎构建正确。

但是，如果我故意在源代码中出错，则运行

~/WORKING_DIRECTORY$ mm art

它仍然在构建，这意味着新文件根本没有被编译。请参阅屏幕截图。

重建模块的正确方法是什么？

模块清洗：

cd $ANDROID_BUILD_TOP
make clean-module_name

艺术项目有多个目标模块。您应该为它们一一使用清洁。
