flavorDimensions gradle 错误 - Android Studio 3.0 Canary 1

Question

我想将我的项目升级到 Android Studio 3.0 Canary 1 和 gradle:3.0.0-alpha1 插件，但是我对包含项目的风格的正确定义有疑问。

我遵循了 Google 的官方迁移指南：https://developer.android.com/studio/preview/features/new-android-plugin-migration.html

在我的主应用 build.gradle 中，我按照迁移指南的建议定义了“myflavor”flavorDimensions：

android {
    flavorDimensions "myflavor"

    productFlavors {
        dev {
            dimension "myflavor"
            minSdkVersion 21
        }
        prod {
            dimension "myflavor"
            minSdkVersion 16
        }
    }

    buildTypes {
        debug {
            signingConfig signingConfigs.debug
        }

        release {
            debuggable false

            signingConfig signingConfigs.release

            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
}

dependencies {
    compile project(':util')
}

在我包含的 :util 模块（生产者）中，我尝试在没有定义 flavorDimensions、productFlavors 和 buildTypes 的情况下包含它。我收到以下 gradle 错误：

Error:Could not resolve all dependencies for configuration ':app:prodDebugCompileClasspath'.
  Cannot choose between the following configurations on project :util:
    - debugApiElements
    - releaseApiElements
  All of them match the consumer attributes:

        - Found com.android.build.gradle.internal.dependency.AndroidTypeAttr 'AndroidTypeAttr{name=Aar}' but wasn't required.

        - Found com.android.build.gradle.internal.dependency.VariantAttr 'VariantAttr{name=release}' but wasn't required.
        - Required myflavor 'ProductFlavorAttr{name=prod}' but no value provided.
        - Required org.gradle.api.attributes.Usage 'for compile' and found compatible value 'for compile'.

在 :util 中定义与 main :app 中相同的 flavorDimensions、productFlavors 和 buildTypes 时，我收到以下错误消息：

包含我的 :util lib 而不出现错误的正确方法是什么？

Answer 1

似乎是 Gradle 构建过程中的一个错误，我不太确定它到底为什么不起作用。我被困了一段时间，但我能够通过改变来解决它

compile project(':util')

到

compile project(path: ':util', configuration: 'default')

让我知道这是否适合你！

Answer 2

我在使用 Canary 2 时遇到了类似的问题，但建议的解决方案不起作用。显然有一种方法可以使用本地库或项目中的实现：

// This is the old method and no longer works for local
// library modules:
// debugCompile project(path: ':foo', configuration: 'debug')
// releaseCompile project(path: ':foo', configuration: 'release')

// Instead, simply use the following to take advantage of
// variant-aware dependency resolution. You can learn more about
// the 'implementation' configuration in the section about
// new dependency configurations.
implementation project(':foo')

Reference from Studio Documentation.

Answer 3

我通过使用 gradle 4.3（使用 Android Studio 3.0）解决了这个问题

将其与 Android Studio 3.0 一起使用：

1. 在此处下载二进制文件：https://gradle.org/releases/
2. 在 Android Studio 中配置本地 gradle 二进制文件，在首选项下...

1. 然后根据您的要求，在您的 gradle 文件中将 compile 替换为 implementation 或 api。

参考： https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

另外：确保您的外部模块（即 util）与您的应用程序具有相同的风格，否则您将收到此处列出的错误：Gradle 4.0 Unable to find a matching configuration

Answer 4

来自https://issuetracker.google.com/issues/65867056：

您应该在根 build.gradle 中只有一个 buildScript 块。 如果您使用的是 Composite 构建，由于 Gradle 的限制，我们的插件目前不支持此功能。

编辑：我想这现在适用于最新版本的 gradle
