Android Studio依赖冲突(程序类型已经存在)

Question

我的项目中有一个 RecyclerView，但我无法构建它。

这是我的 build.gradle 文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "app_name"
        minSdkVersion 27
        targetSdkVersion 27
        versionCode 5
        versionName "1.0.4"
    }
    buildTypes {
        release {
            initWith(buildTypes.debug)
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
    compileOptions {
        targetCompatibility 1.8
        sourceCompatibility 1.8
    }
}

dependencies {
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    implementation 'com.android.support:recyclerview-v7:27.1.1'
//    implementation 'com.android.support:support-v4:27.1.1'
    testImplementation 'junit:junit:4.12'
    compileOnly 'com.google.android.things:androidthings:1.0'
    implementation 'com.google.android.things.contrib:driver-bmx280:1.0'
    implementation 'com.google.android.things.contrib:driver-button:1.0'
    implementation 'com.google.android.things:cloud-iot-core:1.0.0'
    implementation 'com.eclipsesource.minimal-json:minimal-json:0.9.5'
}

当我构建时，我从这三个消息中添加一个:

Program type already present: android.support.v4.content.Loader Message{kind=ERROR, text=Program type already present: android.support.v4.content.Loader, sources=[Unknown source file], tool name=Optional.of(D8)}

Program type already present: android.support.v4.app.TaskStackBuilder Message{kind=ERROR, text=Program type already present: android.support.v4.app.TaskStackBuilder, sources=[Unknown source file], tool name=Optional.of(D8)}

Program type already present: android.support.v4.content.LocalBroadcastManager$ReceiverRecord Message{kind=ERROR, text=Program type already present: android.support.v4.content.LocalBroadcastManager$ReceiverRecord, sources=[Unknown source file], tool name=Optional.of(D8)}

我试图排除这种依赖:

implementation ('com.android.support:recyclerview-v7:27.1.1') {
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'android.support.v4.content.Loader'
    exclude module: 'android.support.v4.content.LocalBroadcastManager$ReceiverRecord'
    exclude module: 'android.support.v4.app.TaskStackBuilder'
}

但我仍然有同样的错误。我该如何解决这个问题？

编辑:我在 Android Studio 中做了一个 androidDependencies 并获得了这个:

Executing tasks: [androidDependencies]

Configuration on demand is an incubating feature.

Answer 1

答案是写:

implementation ('com.google.android.things:cloud-iot-core:1.0.0') {
    exclude module: 'support-v4'
}

'support-v4' 是 cloud-iot-core 的实习生依赖。
