Maven:无法检索插件描述符错误

Question

我配置了 Maven 3.0.3 并尝试通过以下命令下载使用原型(prototype)的示例项目:

mvn archetype:generate -DarchetypeGroupId=org.graniteds.archetypes 
                       -DarchetypeArtifactId=graniteds-tide-spring-jpa-hibernate 
                       -DgroupId=org.example 
                       -DartifactId=gdsspringflex 
                       -Dversion=1.0-SNAPSHOT

(来自此链接的命令:http://java.dzone.com/articles/enterprise-ria-spring-3-flex-4)

我得到了这个错误:

我尝试搜索一些与此类似的帖子，但找不到答案。我尝试更改 settings.xml 中的代理设置，但它仍然不起作用。你能帮帮我吗？

Answer 1

我有同样的错误。在我的例子中，我使用的是 Netbeans 7.1.2，我发布这个是因为也许有人和我一样结束了。

我尝试从 GUI 配置代理选项，但文档说 Maven 不读取这些选项。所以我查看了 NetBeans 常见问题解答 here :

主要你要做的就是在

下创建(如果不存在的话)一个settings.xml

user.home/.m2/settings.xml

如果没有可以复制

netbeans.home/java/maven/conf/settings.xml

然后取消注释，否则只需填写此部分:

<proxies>
 <proxy>
   <active>true</active>
   <host>myproxy.host.net</host>
   <port>80</port>
 </proxy>
</proxies>

你必须检查你的代理配置并在那里替换它
