安卓开发工具Android Studio 3.0 Canary 1: 项目刷新失败

Question

我尝试在这个新的Android Studio 3.0 Canary 1中加载我的项目。它在之前的Android Studio版本2.4预览7中运行得非常完美。

我遇到了以下错误：

Error:Could not resolve all dependencies for configuration ':sample:devCompileClasspath'.
Project :sample declares a dependency from configuration 'devCompile' to configuration 'dev' which is not declared in the descriptor for project :library.

我的Gradle配置如下：

项目级别的构建 Gradle：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha1'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Gradle库模块：

apply plugin: 'com.android.library'
apply plugin: 'checkstyle'

        release {
            shrinkResources false
            minifyEnabled false
        }
    }
}

repositories {
    flatDir{
        dirs '../library/libs'
    }
    mavenLocal()
    jcenter()
}

configurations {
    releaseCompile
    stagingCompile
    devCompile
}

dependencies {
    compile 'com.android.support:appcompat-v7:25.3.1'
    releaseCompile (project(path: ':library', configuration: 'release')) {
        transitive = true
    }
    stagingCompile (project(path: ':library', configuration: 'staging')) {
        transitive = true
    }
    devCompile (project(path: ':library', configuration: 'dev')) {
        transitive = true
    }
}

有人遇到过同样的问题吗？

Answer 1

请查看迁移提示：使用Flavor Dimensions进行变体感知的依赖管理 如其所述：

Plugin 3.0.0包含了一种新的依赖机制，当消耗库时自动匹配变体。这意味着应用程序的调试变体会自动消耗库的调试变体，以此类推。当使用flavors时，应用程序的redDebug变体将消耗库的redDebug变体。为使其正常工作，插件现在要求所有flavors属于一个命名的flavor维度——即使您只打算使用单个维度。否则，您将会得到以下构建错误：

Error:All flavors must now belong to a named flavor dimension. 
The flavor 'flavor_name' is not assigned to a flavor dimension.

为了解决这个错误，请按照下面的示例将每个flavor分配到一个命名维度上。由于插件现在负责依赖匹配，所以您应该仔细命名flavor维度。例如，如果您的所有应用程序和库模块都使用foo维度，则插件匹配哪些flavor的控制权会更少。

// Specifies a flavor dimension. flavorDimensions "color"

 productFlavors {
      red {
       // Assigns this product flavor to the 'color' flavor dimension.
       // This step is optional if you are using only one dimension.
       dimension "color"
       ...
     }

     blue {
       dimension "color"
       ...
     }

Answer 2

  flavorDimensions "mode"
productFlavors {
    dev {
        // Assigns this product flavor to the "mode" flavor dimension.
        dimension "mode"
        versionName "1.2"
        versionCode 02
    }
    uat {
        // Assigns this product flavor to the "mode" flavor dimension.
        dimension "mode"
        versionName "1.2"
        versionCode 2
    }
    live {
        // Assigns this product flavor to the "mode" flavor dimension.
        dimension "mode"
        versionName "1.0.1"
        versionCode 01
    }
}

这对我很有帮助！

在你的情况下，你只需要创建一个flavorDimensions变量，并在dev块内分配值。

flavorDimensions "任何值"

dev.initWith(buildTypes.debug)

    dev {
        dimension "anyvalue"
        applicationIdSuffix ".dev"
    }

这应该会有所帮助。

请注意，您还需要在上一级别中定义该维度类型 productFlavors。像这样：flavorDimensions "mode" productFlavors { ... } - ClayHerendeen
