问题描述与处理处理

1、问题描述
plugins {
    id 'com.android.application'
}

android {
    compileSdk 34

    defaultConfig {
        applicationId "com.my.dialog"
        minSdk 21
        targetSdk 34
        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
    }
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.3.0'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.activity:activity:1.8.0'

    androidTestImplementation 'androidx.test.ext:junit:1.1.5'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Go to the documentation to learn how to Fix dependency resolution errors.
2、问题原因

  1. 项目中同时包含了不同版本的 Kotlin 标准库模块（Kotlin 1.8.22 与 Kotlin 1.6.21）

  2. 项目可能直接依赖与间接依赖了不同版本的 Kotlin 标准库模块，例如，项目的主代码可能依赖于 Kotlin 1.5.x 版本，而某个第三方库则可能依赖于 Kotlin 1.4.x 版本

3、处理策略
  • 在模块级 build.gradle 文件中，添加如下配置，BOM 是一种管理项目依赖版本的方式，它确保了所有 Kotlin 相关的库和插件都使用兼容的版本，从而避免了版本冲突的问题
dependencies {
...
implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))
}
