Question

我在Android Studio 3.1.1上使用Gradle 4.4和Gradle-Android插件3.1.1。

我有2种口味'a'和'b'，由于以下错误，我无法构建我的项目：

Cannot choose between the following configurations of project :app:
  - aDebugMetadataElements
  - bDebugMetadataElements
All of them match the consumer attributes:
  - Configuration 'aDebugMetadataElements':
      - Required com.android.build.api.attributes.BuildTypeAttr 'debug' and found compatible value 'debug'.
      - Found com.android.build.api.attributes.VariantAttr 'aDebug' but wasn't required.
      - Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Metadata' and found compatible value 'Metadata'.
      - Found dim 'a' but wasn't required.
  - Configuration 'bDebugMetadataElements':
      - Required com.android.build.api.attributes.BuildTypeAttr 'debug' and found compatible value 'debug'.
      - Found com.android.build.api.attributes.VariantAttr 'bDebug' but wasn't required.
      - Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Metadata' and found compatible value 'Metadata'.
      - Found dim 'b' but wasn't required.

app build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "me.xyz.flavors"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        debug{
            testCoverageEnabled true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    flavorDimensions "dim"
    productFlavors{
        a{
            dimension "dim"
        }
        b{
            dimension "dim"
        }

    }


}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation project(':base')
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'

    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

base-feature build.gradle：

apply plugin: 'com.android.feature'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
    compileSdkVersion 27
    baseFeature true
    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"

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

    }

    buildTypes {
        aDebug {
            testCoverageEnabled true
        }
        bDebug {
            testCoverageEnabled true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    application project(':app')
    api 'com.android.support:appcompat-v7:27.1.1'
    api 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    api "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
}

到目前为止，我尝试了以下解决方案，但没有运气：

修改：

根据评论和一个答案，我尝试给两种口味提供不同的applicationIdSuffix，但问题仍然存在：

productFlavors{
        a{
            applicationIdSuffix ".a"
            dimension "dim"
        }
        b{
            applicationIdSuffix ".b"
            dimension "dim"
        }

    }

Answer 1

感谢用户TWL向我指出google samples for instant apps, with an example for flavors。

我们还需要在所有功能模块，应用程序模块和即时应用程序模块中使用flavor声明。截至今天，可以使用插件版本3.1.1跳过库模块。换句话说，将此部分包含在所有功能和已安装/即时模块中：

flavorDimensions "dim"
productFlavors{
    a{
        dimension "dim"
    }
    b{
        dimension "dim"
    }
}

Answer 2

首先，您不必在模块中具有匹配的口味。您可以告诉它回退到默认的构建类型。

通过使用matchingFallbacks

buildTypes {
    aDebug {
        testCoverageEnabled true
        matchingFallbacks = ['debug']
    }
    bDebug {
        testCoverageEnabled true
        matchingFallbacks = ['debug']
    }
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        // This one already looks for 'release' which is added by default, so no need for fallback
    }
}

Answer 3

您似乎没有指定a和b包名称的差异。以下是我在 AS 2.3.3的flavor级别com.android.tools.build:gradle:2.3.1中针对API 25的app功能以及build.gradle的工作实施< /强>：

apply plugin: 'com.android.application' android { compileSdkVersion 25 buildToolsVersion "25.0.3" defaultConfig { applicationId "com.example" minSdkVersion 14 targetSdkVersion 25 versionCode 1 versionName "1.00" } signingConfigs { config { storeFile file(STORE_PATH) keyAlias KEY_ALIAS keyPassword KEY_PASSWORD storePassword KEYSTORE_PASSWORD } } productFlavors { nosync { applicationIdSuffix ".nosync" versionNameSuffix '-nosync' signingConfig signingConfigs.config } sync { signingConfig signingConfigs.config } } buildTypes { release { debuggable false minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' signingConfig signingConfigs.config } debug { debuggable true signingConfig signingConfigs.config } } dependencies { ... }

看一下差异

applicationIdSuffix ".nosync" versionNameSuffix '-nosync'

介于nosync和sync之间。它会更改nosync apk的包名称。

无法在多风味应用程序中构建功能模块
