Android程序类型已经存在错误

Question

为了找到解决方案(他们提到 gradle 文件中重复的包名称、AndroidManifests 中的重复以及依赖版本不匹配)，我经历了几个具有相同错误的线程，但没有一个与我的情况相同。这是我在构建应用程序时收到的错误消息:

Program type already present: ff.ecochallenges.game.BuildConfig
Message{kind=ERROR, text=Program type already present: ff.ecochallenges.game.BuildConfig, sources=[Unknown source file], tool name=Optional.of(D8)}

我的应用程序 gradle 文件如下所示:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "ff.ecochallenges"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation fileTree(include: ['*.jar'], dir: 'libs')

}

apply plugin: 'com.google.gms.google-services'

我添加的新库(游戏)的 gradle 是这样的:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 27



    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

当我在我的应用程序 gradle 中注释掉“implementation project(":game")”行时，它构建时没有错误，所以我确定“game”gradle 有问题，但我找不到它是什么。

Answer 1

其中一行可能定义 ff.ecochallenges.game 两次:

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation project(":garden-release")
implementation project(":game")

假设 libs 目录中包含一个 .jar

或模块 garden-release 可能依赖于模块 game。

例如。你可以在模块 garden-release 中使用 api project(":game")。
