java - 在 Gradle 上构建 APK 时出现重复类错误

Question

当我偶然发现这个错误时，我正在将我的项目迁移到 Gradle:

程序类型已存在:com.google.android.maps.GestureDetector$GestureHandler

该项目有2个模块，1个是应用程序，另一个是核心。
在 app build.gradle 中，我导入了模块 core和 root /libs (我在旧项目结构中使用的 .jar)，而核心也需要/libs 目录。

应用程序构建.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 28
    }

    buildTypes {
        release {
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }

        debug {
        }
    }
}

dependencies {
    implementation fileTree(include: '*.jar', dir: "$rootProject.projectDir/libs")
    implementation project(':core')
}

核心 build.gradle

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    publishNonDefault true

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }

        debug {
        }
    }
}


dependencies {
    implementation fileTree(include: '*.jar', dir: "$rootProject.projectDir/libs")
}

详细错误:

我对新的构建工具也有这个问题。但是，如果您使用构建工具 26，则可以避免此问题。
