*该教程为mac环境下*
由于电脑原因重新安装了系统，之后安装android studio跑项目的时候出现如下错误
Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.
1、android studio版本为如下：
Android Studio 版本信息
SDK Platforms
SDK Tools
android {
compileSdkVersion 31
buildToolsVersion "31.0.0"
defaultConfig {
applicationId "com.civiccloud.myapplication"
minSdkVersion 21
targetSdkVersion 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
2、错误信息如下：
Executing tasks: [:app:assembleDebug] in project /Users/yau/Downloads/demo
Build-tool 31.0.0 is missing DX at /Users/yau/softSdk/Android/SDK/build-tools/31.0.0/dx
Build-tool 31.0.0 is missing DX at /Users/yau/softSdk/Android/SDK/build-tools/31.0.0/dx
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.

3、很显然错误信息告诉我们丢失了dx文件解决方案如下：
1.先找到Android 的安装目录
echo $ANDROID_HOME // /Users/softSdk/Android/SDK
2.修改文件名称
mv /Users/softSdk/Android/SDK/build-toolsd/31.0.0/8 /Users/softSdk/Android/SDK/dx
mv /Users/softSdk/Android/SDK/build-tools/lib/31.0.0/d8.jar /Users/softSdk/Android/SDK/build-tools/31.0.0/lib/dx.jar
至此教程结束
