使用 Gradle 控制台命令的问题 (gradlew)

Question

我正在控制台中使用 gradlew 命令编译一个项目，但出现此错误：

我不知道出了什么问题，这些是我的 gradle 依赖项：

对于应用程序模块：

dependencies {
    compile project(':capLibrary')
    compile 'com.google.android.gms:play-services:7.5.0'
}

对于库模块（capLibrary）：

dependencies {
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

这是库 (capLibrary) 的完整 gradle.build 文件：

apply plugin: 'com.android.library'

android {
    compileSdkVersion 'Google Inc.:Google APIs:22'
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 10
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
        debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

这是应用程序模块的完整 gradle.build：

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 'Google Inc.:Google APIs:22'
        buildToolsVersion "22.0.1"

        defaultConfig {
            applicationId "com.example.launcher"
            minSdkVersion 10
            targetSdkVersion 10
        }

        signingConfigs {
            release {
                storeFile file("dummy")
                storePassword "dummy"
                keyAlias "dummy"
                keyPassword "dummy"
            }
        }

        buildTypes {
            release {
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            }
            debug {
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            }
        }
    }

    dependencies {
        compile project(':capLibrary')
        compile 'com.google.android.gms:play-services:7.5.0'
    }

Answer 1

运行 Android SDK 管理器。

tip: in console write >> android [enter]

并从 Android SDK Manager / Extras 安装：

Android 支持存储库
Google 存储库

Answer 2

无法找到 com.android.support:support-v4:22.2.1。找不到 com.google.android.gms:play-services:7.5.0.

库项目找不到这些支持库。

请检查这个。看看这是否有帮助。

转到项目结构，然后从模块 select 您的 capLibrary 模块。检查它的依赖关系。如果不存在，请添加 v4 支持并播放服务并构建项目。
