Question

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的新手所以如果这很容易解决请原谅我用Google搜索了问题并研究了错误页面，但我找不到这个问题的解决方案。但每次我尝试我都会得到这样的错误：

通过github发布我的问题我得到了Info，我必须更改compat pom.xml中从r4到r6的依赖关系，所以我尝试了它并将其改为：

<android.support.version>r4</android.support.version>

到此：

<android.support.version>r6</android.support.version>

但是这没有用，所以我继续前进并尝试了这种方式。我从这里编辑了Depencies部分：

            <dependency>
            <groupId>android.support</groupId>
            <artifactId>compatibility-v4</artifactId>
            <version>${android.support.version}</version>
        </dependency>

到此：

            <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：

compatibility-v6和兼容性-R6

但没有任何效果。我还检查了.m2目录，它不存在。如果Maven安装得很好，我也会进行修复。我希望有人可以帮助我。

最好的问候

Answer 1

由于Manfred和Jake

，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规范

<dependency>
  <groupId>com.google.android</groupId>
  <artifactId>support-v4</artifactId>
  <version>r6</version>
</dependency>

Answer 2

maven的工作方式非常简单，首先将所需的jar依赖项从Internet下载到本地maven存储库，在以后构建应用程序时，它会从本地maven存储库中解析所有必需的jar文件。

你的问题：
Maven正试图从http://r.jakewharton.com/maven/release/android/support/compatibility-v4/r4/下载一个jar文件，自己试试，这是一个死链接。这通常意味着开发人员不能正确维护他们的maven版本。

闷闷不乐：
我想GitHub上的this post来自您，您需要使用maven-android-sdk-deployer，请查看此处的“如何使用”部分。基本上，你需要运行maven-android-sdk-deployer将你当地的Android SDK目录中所需的jar（目前还没有可用的）复制到你的maven本地存储库中，正如我所说，如果你没有明确指定它，maven总是从你当地的maven存储库中解析jar文件。

Maven Repo中缺少“compatibility-v4-r4.jar”
