Eclipse Java EE 新 Maven 项目：无法解析原型

Eclipse Java EE New Maven Project: Could not resolve archetype

提问by Man Friday

I am using the latest Eclipse Java EE(Kepler) and trying to create a Maven project. When I attempt to do this, and finally click the Finish button, I get this error:

我正在使用最新的Eclipse Java EE(Kepler) 并尝试创建一个 Maven 项目。当我尝试执行此操作并最终单击“完成”按钮时，出现此错误：

Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE from any of the configured repositories.

无法从任何配置的存储库解析原型 org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE。

All I have done in terms of "set-up" is install Eclipse Java EE (I also installed the main eclipse standard 4.3 earlier). I am also on a work computer, and a proxy test I ran returned the result: This request appears to have come via a proxy.

我在“设置”方面所做的就是安装 Eclipse Java EE（我之前还安装了主 Eclipse 标准 4.3）。我也在一台工作计算机上，我运行的代理测试返回了结果：此请求似乎是通过代理来的。

This has driven me nearly insane, so any help would be great! Thanks!

这让我几乎疯了，所以任何帮助都会很棒！谢谢！

Please verify, in Eclipse, Windows > Preferences > Maven > User Settings, please check the User settings file (settings.xml) exists and the proxy setting inside that file is correctly pointed to your proxy server.

请验证，在 Eclipse 中，Windows > 首选项 > Maven > 用户设置，请检查用户设置文件 (settings.xml) 是否存在，并且该文件中的代理设置是否正确指向您的代理服务器。

Remove C:\Users\ {your username}\ .m2\repository\org\apache\maven folder and try to create your maven project again.

删除 C:\Users\ {your username}\ .m2\repository\org\apache\maven 文件夹并再次尝试创建您的 maven 项目。

Besides what have mentioned, it's required for me to modify proxy protocol from httpsto http.

除了上面提到的，我需要将代理协议从https修改为http。

Adding the following inside "mirrors" section in the user setting.xml file.

在用户 setting.xml 文件的“镜像”部分中添加以下内容。

<!-- mirrors so we can control the access of artifacts and avoid going to 
    the internet for artifact metadata -->
<mirrors>
    <mirror>
        <id>maven repo</id>
        <url>http://repo.maven.apache.org/maven2</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
</mirrors>

The official Maven 2 repository is at http://repo.maven.apache.org/maven2hosted in the US, or http://uk.maven.org/maven2hosted in the UK.

官方 Maven 2 存储库位于美国托管的http://repo.maven.apache.org/maven2或英国托管的http://uk.maven.org/maven2。
