解决 Android Studio 中重复的外部库

Question

当我检查我的 Android Studio 项目中的外部库时，我看到不同版本的重复库。

有什么办法可以找出原因。

我绝对不会添加多个依赖项。但不确定，是什么原因造成的。 这是我的 build.gradle 文件；

// 顶级构建文件，您可以在其中添加所有子项目/模块通用的配置选项。

buildscript {
    
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.3.8'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.6.1'

    }


}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        maven() {
            url "https://oss.sonatype.org/content/repositories/snapshots"
        }
        maven {
            url "s3://android.maven.s3.amazonaws.com"
            credentials(AwsCredentials) {
                accessKey ""
                secretKey ""
            }
        }
    }
}

subprojects {

    project.evaluationDependsOn(':_ABT')
//[PART TO ADD START]
    project.configurations.all {

        resolutionStrategy.eachDependency { details ->

            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.0"
            }
        }
    }
//[PART TO ADD END]
}

ext {
    supportLibVersion = "28.0.0"
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是build.gradle的依赖文件；

这些是一些重复的库。例如，我有 3 个用于 android-core 的库：

androidx.core:core:1.3.1@aar
androidx.core:core:1.3.2@aar
androidx.core:core:1.5.0@aar

你可以在下面看到更多：

有没有什么方法可以查出是谁调用了这些库来找出它们的来源？

提前致谢！

Answer 1

这可能是因为所谓的传递依赖。假设您正在使用 android 核心库版本 1.5.0，并且您还使用另一个库，例如 XyzImage 库。现在 XyzImage 库内部依赖于 android 核心库版本 1.2.0。现在由于这个原因，您的应用程序依赖树如下所示：

-- Your App
 +-> AndroidCore@1.5.0
 +-> XyzImageLibrary@1.1.0
     +-> AndroidCore@1.2.0

现在 XyzImageLibrary 可以配置它的 gradle 文件，这样 gradle 在处理 XyzImageLibrary 文件时应该只使用 1.2.0 版本的 AndroidCore 库。因此，gradle 需要下载同一个库的多个版本。您可以按照解决方案https://stackoverflow.com/a/35235229/5309486 查找您的Android App 的依赖关系树。

Answer 2

试试

plugin{
   id 'com.android.application'
   id 'com.google.gms.google-services'
 }

在您的应用级别 gradle 中，而不是 apply plugin
