一、报错信息

Android Studio 编译时 , 报如下错误 :

Execution failed for task ':core:checkDebugAarMetadata'.> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction   > The minCompileSdk (33) specified in a     dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)     is greater than this module's compileSdkVersion (android-32).     Dependency: androidx.core:core:1.9.0.     AAR metadata file: C:\Users\octop\.gradle\caches\transforms-2\files-2.1\c6e343978c6a27069301c93169f4abc4\core-1.9.0\META-INF\com\android\build\gradle\aar-metadata.properties.* Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

二、解决方案

方案一 : 修改编译版本

方法一 : 直接修改编译版本 ;

问题是 androidx.core:core:1.9.0. 依赖库中 要求的 minCompileSdk 为 33 , 本应用的编译版本为 32 , 这里设置为 33 即可解决 , 但是这样设置会造成其它问题 ;

android {    compileSdkVersion 32    buildToolsVersion "32.0.0"    defaultConfig {        applicationId "kim.hsl.core"        minSdkVersion 18        targetSdkVersion 32        versionCode 1        versionName "1.0"        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"    }}

方案二 : 处理依赖库

下面从依赖分析的角度解决上述问题 ;

执行

gradlew app:dependencies --configuration releaseRuntimeClasspath

命令 , 查看依赖库 , 输入内容如下 :

D:\002_Project\002_Android_Learn\Componentization>gradlew app:dependencies --configuration releaseRuntimeClasspathWARNING:: Please remove usages of `jcenter()` Maven repository from your build scripts and migrate your build to other Maven repositories.This repository is deprecated and it will be shut down in the future.See http://developer.android.com/r/tools/jcenter-end-of-service for more

分析整个依赖 , 发现到处都有 androidx.core:core 依赖库 , 而且版本都不一样 ;

但是使用到 androidx.core:core:1.9.0 版本的情况 , 只有在 androidx.core:core-ktx:1.9.0 依赖库中出现了 ;

其它的依赖库都使用的是低版本的 androidx.core:core 依赖库 ;

直接注释掉 androidx.core:core-ktx:1.9.0 依赖库 , 或者将其降低为 androidx.core:core-ktx:1.8.0 , 都可以解决这个问题 ;

由

dependencies {    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"    implementation 'androidx.core:core-ktx:1.9.0'    implementation 'androidx.appcompat:appcompat:1.5.1'    implementation 'com.google.android.material:material:1.6.1'    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'    testImplementation 'junit:junit:4.+'    androidTestImplementation 'androidx.test.ext:junit:1.1.3'    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'}

改为

dependencies {    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"    implementation 'androidx.core:core-ktx:1.8.0'    implementation 'androidx.appcompat:appcompat:1.5.1'    implementation 'com.google.android.material:material:1.6.1'    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'    testImplementation 'junit:junit:4.+'    androidTestImplementation 'androidx.test.ext:junit:1.1.3'    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'}

只修改了 androidx.core:core-ktx 依赖库的版本由 1.9.0 改为 1.8.0 ;

解决思路 : 某个依赖库报错 , 执行

gradlew app:dependencies --configuration releaseRuntimeClasspath

命令 , 查看该依赖库的依赖关系 , 从属于哪个依赖库 , 与哪个依赖库产生冲突 , 进而解决依赖冲突问题 ;
