我在 Eclipse 中有一个 Maven 项目，如果我尝试运行，Maven > Update project我会收到以下错误

Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from http://repo.maven.apache.org/maven2was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from/to central (http://repo.maven.apache.org/maven2): java.net.ConnectException: connection timed out to http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.5/maven-resources-plugin-2.5.pom

org.apache.maven.plugins:maven-resources-plugin:pom:2.5 从http://repo.maven.apache.org/maven2传输失败被缓存在本地存储库中，直到更新间隔才会重新尝试解析中央的已过期或强制更新。原始错误：无法传输工件 org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from/to central ( http://repo.maven.apache.org/maven2): java.net.ConnectException:与http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.5/maven-resources-plugin-2.5.pom 的连接超时

• I tried to run Maven with the embedded installation and an external one - same result.
• I don't have any proxy set up in Eclipse and I don't need one.
• I do not reference the plugin in my POM.
• Running mvn eclipse:eclipsein console works perfectly.
• I'm using Eclipse Kepler and m2e 1.4.0.201.

• 我尝试使用嵌入式安装和外部安装运行 Maven - 结果相同。
• 我没有在 Eclipse 中设置任何代理，我也不需要。
• 我没有在我的 POM 中引用该插件。
• 运行mvn eclipse:eclipse在控制台完美。
• 我正在使用 Eclipse Kepler 和 m2e 1.4.0.201。

The parent POM is

父 POM 是

<parent>
    <groupId>org.sonatype.oss</groupId>
    <artifactId>oss-parent</artifactId>
    <version>7</version>
</parent>

Anyone have any idea why?

任何人都知道为什么？

Here's the error I was getting initially:

这是我最初遇到的错误：

Failure to transfer org.sonatype.oss:oss-parent:pom:9 from http://repo.maven.apache.org/maven2was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.sonatype.oss:oss-parent:pom:9 from/to central (http://repo.maven.apache.org/maven2): Address family not supported by protocol family: connect

org.sonatype.oss:oss-parent:pom:9 从http://repo.maven.apache.org/maven2传输失败 被缓存在本地存储库中，直到 central 的更新间隔已过才会重新尝试解析或强制更新。原始错误：无法传输工件 org.sonatype.oss:oss-parent:pom:9 from/to central ( http://repo.maven.apache.org/maven2)：协议系列不支持地址系列：连接

I didn't need to introduce any additional maven plugins, simply enclosing the existing plugins inside <pluginManagement>tag as described here: How to solve "Plugin execution not covered by lifecycle configuration" for Spring Data Maven Buildssolved it for me - hopefully it will help someone else as well.

我不需要引入任何额外的 Maven 插件，只需将现有插件包含在<pluginManagement>标签中，如下所述：如何解决 Spring Data Maven Builds 的“生命周期配置未涵盖的插件执行”为我解决了这个问题 - 希望它会帮助某人其他也一样。
