android - Gradle 找不到依赖项(Android 支持库)

Question

我有一个问题，Gradle 找不到我的依赖项(Android 支持库)。

我的 build.gradle 看起来像这样:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/FlurryAgent.jar')
    compile group: 'com.google.android', name: 'support-v4', version: 'r7'
    compile files('libs/YouTubeAndroidPlayerApi.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 17
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

当我构建(在命令行上，没有 IDE)时，我收到以下消息:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'AndroidCalculator'.
> Failed to notify project evaluation listener.
   > Could not resolve all dependencies for configuration ':compile'.
      > Could not find com.google.android:support-v4:r7.
        Required by:
            :AndroidCalculator:unspecified

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

为什么不允许我这样添加 Android 支持库？

您已声明 存储库依赖项，但尚未声明 存储库。因此无法解决依赖关系。 (buildscript block 中的存储库/依赖项与主构建脚本中的存储库/依赖项严格分开。)
