java - 创建 Maven 项目，无法解析原型(prototype)，连接被拒绝

Question

我怀疑我有 Maven 代理问题。当我创建一个新项目时:

1) 文件 -> 新建 -> Maven 项目

2)我选择 archetype :在 org.apache.maven.archetypes -> ma​​ven-archetype-webapp

3)我收到此错误:

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

Creating maven-archetype-webapp' has encountered a problem. Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webap p:RELEASE from any of the configured repositories.

详细信息:

我们可以看到问题的根源:连接被拒绝:连接

我已经这样做了:

1) 窗口 -> 首选项 -> 常规 -> 网络连接。我为 HTTP 协议(protocol)输入了手动以及代理的url和端口 。它之所以有效，是因为在此之前，Spring Tool Suite 不想更新。之后就没事了。

2) 窗口 -> 首选项 -> Maven -> 用户设置。在全局设置中，为空。在用户设置中，我将路径设置为settings.xml。在这个文件中，我有:

<settings>
  <proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>my.proxy.fr</host>
      <port>3128</port>
    </proxy>
  </proxies>
</settings>

在本主题中: Create a Maven project in Eclipse complains "Could not resolve archetype"通过添加远程目录 http://repo1.maven.org/maven2/archetype-catalog.xml 解决了问题。对我来说，它说目录是空的。

我的配置:Windows 7 Pro 64 位，基于 Eclipse Luna SR1 (4.4.2) 的 Spring 工具套件 3.6.4.RELEASE，Java 版本 8 Update 45，无经过身份验证的代理

为什么我无法创建新的 Maven 项目？

Answer 1

我也遇到了同样的问题，我想在某个时间你试图像我一样在没有互联网连接的情况下创建 Maven 应用程序，这就是导致这个问题的原因。因为第一次 Maven 创建一个空目录并尝试下载创建项目所需的任何内容..在您创建任何 Maven 项目之后，Maven 会一直在该目录中查找，而不从互联网上下载东西。我相信解决此问题的最简单方法是关闭 Eclipse(或 sts)并删除位于(在我的情况下)“c:/Users/myname/.m2”中的 .m2 目录。然后重新打开您正在使用的 IDE。祝你好运
