Gradle错误:配置声明未声明的依赖项

Question

我正在制作我的第一个Android服装应用程序,但我无法让Android Studio工作.首先我得到了错误

 "Project with path ':wear' could not be found in project ':mobile'. 

这是通过添加"include ':wear"来解决的settings.gradle.
但随后出现了一个新错误:

"Error:Module version Test2:mobile:unspecified, configuration 'wearApp' declares a dependency on configuration 'default' which is not declared in the module descriptor for Test2:wear:unspecified" .

我该怎么做才能解决这个错误？

以防万一需要:这里是build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.verbraeken.joost.test2"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    wearApp project(':wear')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.google.android.gms:play-services:8.3.0'
    compile 'com.android.support:design:23.1.1'
}

settings.gradle:

include ':mobile'
include ':wear'

在Android Studio 3.0中,迁移到新插件的文档说:

dependencies {
    // 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')

    // You can, however, keep using variant-specific configurations when
    // targeting external dependencies. The following line adds 'app-magic'
    // as a dependency to only the 'debug' version of your module.

    debugImplementation 'com.example.android:app-magic:12.3'
}

所以改变这个

    debugCompile project(path: ':foo', configuration: 'debug')
    releaseCompile project(path: ':foo', configuration: 'release')

对此

    implementation project(':foo')

错误:模块版本Test2:mobile:未指定,配置'wearApp'声明对配置'default'的依赖

这意味着模块(在您的情况下为wearApp)在build.gradle文件中没有文件或正确的配置build.gradle.

由于您定义了一个模块,settings.gradle您必须build.gradle 为每个模块提供一个模块.

在你的情况下:

root
|-- mobile
|----build.gradle
|-- wear
|----build.gradle
|--build.gradle
|--settings.gradle
