如何将 Android 支持存储库添加到 Android Studio?

问题描述

我正在使用带有外部 Android SDK 的 Android Studio.我已经安装了支持库和支持存储库.支持存储库位于:

I'm using Android Studio with an external Android SDK. I have installed the support library and the support repository. The support repository is in:

~/Development/Tools/android/sdk/extras/android/m2repository

当我在 build.gradle 文件中向支持库添加依赖项时，例如:

When I add a dependency to the support library in the build.gradle file, like:

...

repositories {
    mavenCentral()
}

...

dependencies {
   compile "com.android.support:support-v4:18.0.+"
}

Android Studio 找不到支持库(无法解析符号等)，Gradle 也找不到这些库:

Android Studio cannot find the support libraries (cannot resolve symbol etc) and Gradle also cannot find the libraries:

Gradle: A problem occurred configuring project ':TestAndroidStudio'.
> Failed to notify project evaluation listener.
   > Could not resolve all dependencies for configuration ':TestAndroidStudio:_DebugCompile'.
      > Could not find any version that matches com.android.support:support-v4:18.0.+.
        Required by:
            TestAndroidStudio:TestAndroidStudio:unspecified

如何在 Android Studio 和/或 build.gradle 文件中指定 Android 支持存储库的位置?

How do I specify in Android Studio and/or the build.gradle file the location of the Android support repository?

推荐答案

你可能被 此错误 阻止 Android Gradle 插件自动将Android 支持存储库"添加到 Gradle 存储库列表中.如错误报告中所述，解决方法是将 m2repository 目录显式添加为顶级 build.gradle 文件中的本地 Maven 目录，如下所示:

You are probably hit by this bug which prevents the Android Gradle Plugin from automatically adding the "Android Support Repository" to the list of Gradle repositories. The work-around, as mentioned in the bug report, is to explicitly add the m2repository directory as a local Maven directory in the top-level build.gradle file as follows:

allprojects {
    repositories {
        // Work around https://code.google.com/p/android/issues/detail?id=69270.
        def androidHome = System.getenv("ANDROID_HOME")
        maven {
            url "$androidHome/extras/android/m2repository/"
        }
    }
}
