Android.bp编译提示ninja: error: unknown target ‘MODULES-IN-xxx’终极指南

前言

   当我们通过Android.bp编译脚本构建App或者bin执行文件时，可能会莫名的提示ninja: error: unknown target ‘MODULES-IN-xxxxroid-external-AndroidBp’的错误，那么怎么解决呢？好吗，让我带领你一期解决。

注意：这个问题常见于Android 8上面

一.解决办法

### 1.1 错误提示 先看一下错误提示：

build/core/Makefile:1902: warning: overriding commands for target `out/target/product/sl8541e_1h10_go/prodnv.img' build/core/Makefile:34: warning: ignoring old commands for target `out/target/product/sl8541e_1h10_go/prodnv.img' vendor/sprd/build/tasks/sprdbuildota.mk:98: warning: overriding commands for target `out/target/product/sl8541e_1h10_go/sl8541e_1h10_gofu_osll-ota-6.zip' build/core/Makefile:2821: warning: ignoring old commands for target `out/target/product/sl8541e_1h10_go/sl8541e_1h10_gofu_osll-ota-6.zip' ninja: error: unknown target 'MODULES-IN-xxxxroid-external-AndroidBp' 15:33:36 ninja failed with: exit status 1  

### 1.2 修改

这个比较容易解决，一般是在你的Android源码编译根目录，修改顶层的Android.bp然后将你的文件工程路径添加上去，譬如我这里添加的是xxxxroid/external/AndroidBp.

subname = "Android.bp"  build = [      "build/blueprint/Blueprints", ]  subdirs = [      "build/soong", ]  optional_subdirs = [      "art",     "bionic",     "bootable/recovery",     "build/kati",     "build/tools/*",     "dalvik",     "development/*",     "device/*/*",     "external/*",     "frameworks/*",     "frameworks/compile/*",     "frameworks/hardware/interfaces",     "frameworks/opt/net/wifi",     "hardware/*",     "libcore",     "libnativehelper",     "packages/apps/*",     "xxxxroid/external/systool",     "xxxxroid/external/AndroidBp",     "prebuilts/clang/host/linux-x86",     "prebuilts/ndk",      "prebuilts/sdk",     "system/*",     "system/hardware/interfaces",     "system/tools/*",     "test/vts",     "test/vts-testcase/*",     "vendor/*/*",     "vendor/*/*/*" ] 

编译成功：
