我配置了Maven 3.0.3，并尝试通过以下命令使用原型下载示例项目:

I configured Maven 3.0.3 and tried to download a sample project using archetypes with this command:

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: java. dzone/articles/enterprise-ria-spring-3-flex-4 )

(Command from this link : java.dzone/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，但仍然无法正常工作.你能帮我吗?

I tried searching some posts similar to this but couldn't get an answer. I tried changing proxy settings in settings.xml but it still doesn't work. Could you please help me out?

推荐答案

我有相同的错误.就我而言，我正在使用Netbeans 7.1.2，我之所以发布它是因为也许有人最终会和我一样.

I had the same error. In my case I am using Netbeans 7.1.2, I am posting this because maybe someone end up here same as I did.

我试图从GUI配置代理选项，但是文档说maven不读那些.因此，我在此处处检查了NetBeans常见问题解答:

I tried to configure the proxy options from the GUI, but the documentation says that maven doesn't read those. So I checked the NetBeans FAQ here :

主要要做的是在

user.home/.m2/settings.xml

如果没有，可以从

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

然后取消注释(如果已有的话)，否则只需填写此部分:

then uncomment if you already have it otherwise just fill this section:

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