这应该是我朋友的一个工作项目.他在我面前展示了项目,然后我复制了项目,将其作为现有的maven项目导入(我使用的是m2eclipse插件).
然后,发生此错误.每次我尝试使用maven构建内容时都可以重现此错误.
执行mvn依赖:tree,dependency:list或通常的构建包将导致相同的错误.
从eclipse运行'package'构建的错误是:

[INFO] Finished at: Tue Jan 11 …我刚刚下载了Maven,并试图运行"Maven in Five Minutes"页面(http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html)上发现的简单命令.这是命令:
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
当我运行它时,我收到SSL证书的错误,无法从https://repo.maven.apache.org/maven2的中央Maven存储库下载.错误是"SunCertPathBuilderException:无法找到请求目标的有效证书路径".
我坐在公司防火墙后面并正确配置了两者的代理设置http并https通过该settings.xml文件进行访问.我怀疑所有下载Maven并且第一次运行它的人都必须导入Maven存储库的SSL证书,所以问题必须在于代理.有人对这个有经验么？
这是完全调试模式(-X)中的堆栈跟踪:

我试图从代理后面访问maven存储库.我正确配置了settings.xml(我猜是这样......)

但我仍然得到一个错误消息,如...如果我没有配置用户ID /密码获取正确的错误消息,这是HTTP响应代码407- 说需要身份验证.但是,如果我配置正确/不正确的代理身份验证,它总是打印下面的错

我是一个自动生成的代理.
我已经将settings.xml配置为使用此代理,但它仍然无效.Android SDK与我设置的相同代理工作正常.

我还能做些什么让maven工作？
错误:
WARNING: NTLM authentication error: Credentials cannot be used for NTLM authenti
cation: org.apache.maven.wagon.providers.http.httpclient.auth.UsernamePasswordCr

如何获得我的NTLM身份验证信令？
Original error: Could not transfer metadata org.codehaus.mojo/maven-metadata.xml from/to central (http://repo.maven.apache.org/maven2): Not authorized by proxy , ReasonPhrase:Proxy Authorization Required.
这是输出消息.在我的wpad.dat(我从那里获取代理数据),我没有指定的用户名和密码...
我在settigns.xml文件中添加了代理配置,但Maven没有使用它,我通过使settings.xml文件无效来确认这一点.我运行maven install命令更新设置和全局设置以指向正确的文件,仍然没有运气.我正在使用maven3.0.4.
