Android :未能找到com.android.support:support-v4:22.2.1

Question

在我的依赖项中有以下内容：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.github.satyan:sugar:1.3.1'
    compile 'com.android.support:support-v13:+'
}

而且该项目编译得很好，但是当我添加以下内容时：

compile 'com.mohamadamin:persianmaterialdatetimepicker:1.2.1'

我收到以下错误消息：

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not find com.android.support:support-v4:22.2.1.

我找了很多东西，但似乎对我的案子没有任何用处。我怎样才能解决这个问题？

Answer 1

如果您有appcompat-v7:22.1.1，这意味着您应该拥有support-v4:22.1.1。您试图使用的库正在请求support-v4:22.2.1，这是较新的。

确保您的在SDK中是最新的。通常，拥有较旧的工件而不是更新的工件意味着您最近没有更新。
