"compatibility-v4-r4.jar“在Maven Repo中缺失
在过去的两天里，我尝试通过Maven导入这个库：
https://github.com/JakeWharton/Android-ViewPagerIndicator
我不得不说，我是maven的新手，所以如果这个问题很容易解决，请原谅我，我用谷歌搜索了这个问题，并研究了错误页面，但我找不到解决这个问题的方法。但每次我尝试的时候都会得到这样的错误：

<android.support.version>r4</android.support.version>要这样做：
<android.support.version>r6</android.support.version>但这并不管用，所以我继续往前走，并尝试了这种方式。我从下面编辑了依赖项部分：
<dependency>
<groupId>android.support</groupId>
<artifactId>compatibility-v4</artifactId>
<version>${android.support.version}</version>
</dependency>要这样做：
<dependency>
<groupId>android.support</groupId>
<artifactId>compatibility-v4-r6</artifactId>
<version>${android.support.version}</version>
</dependency>我还尝试将"compatibility-v4“替换为：
兼容性-V6和兼容性-R6
但都不管用。我还检查了.m2目录，但它不在那里。我还检查了Maven是否已正确安装，确实如此。我希望有人能帮助我。
诚挚的问候

maven的工作方式非常简单，首先从internet下载所需的jar依赖项到本地maven存储库，稍后构建应用程序时，它会解析本地maven存储库中所有必需的jar文件。
你的问题：
Maven正在尝试从http://r.jakewharton.com/maven/release/android/support/compatibility-v4/r4/下载jar文件，请自己尝试，这是一个死链接。这通常意味着开发人员没有正确地维护他们的maven发行版。
解决方案：
我假设GitHub上的this post来自你，你需要使用maven-android-sdk-deployer，请查看这里的“如何使用”部分。基本上，你需要运行maven- Android - SDK -deployer从你本地的Android SDK目录复制所需的jar文件到maven本地仓库，就像我说的，如果你没有明确指定，maven总是会解析来自你本地maven仓库的jar文件。

多亏了Manfred和Jake，这个支持库现在可以在公共maven存储库中使用
http://www.simpligility.com/2012/01/android-compatibility-library-following-lint/
您只需要使用稍微不同的依赖项规范。
<dependency>
<groupId>com.google.android</groupId>
<artifactId>support-v4</artifactId>
<version>r6</version>
</dependency>https://stackoverflow.com/questions/8608971
