什么可能导致Maven中的“错误传输文件"? [英] What could be causing 'error transferring file' in maven?
问题描述
我已经在debian机器上安装了maven 2.2.1并收到以下错误消息
I have installed maven 2.2.1 on my debian machine and getting the following error
[WARNING] repository metadata for: 'org.apache.maven.plugins' could not be retrieved from repository: central due to an error: Error transferring file: repository.exoplatform.org
我能够找到的与该问题有关的原因通常是由于未正确配置代理设置或防火墙阻止了流量引起的，但我在这台计算机上都没有.另外，我在Windows机器上有相同的设置文件，并且工作正常.
What I have been able to find relating to this problem is its typically caused by not having proxy settings correctly configured or a firewall blocking traffic, but I dont have either on this machine. Also, I have the same settings file on my windows machine and it works fine.
当我陷入困境时，任何建议都将不胜感激.
Any suggestions would be greatly appreciated as I am stumped.

我尝试删除settings.xml并生成一个新的Maven项目.我得到了以下
I tried removing the settings.xml and generating a new maven project. I got the following

我认为这可以排除是settings.xml或pom问题.有没有办法获取有关为什么Maven无法连接到存储库的更多信息?
I think this rules out it being a problem with the settings.xml or a pom. Is there a way to get more information about why maven cant connect to the repository?
推荐答案
只是关闭这一循环-事实证明debian的库可用于Java来解析主机名，这是一个问题.解决方法是为Java应用一个新的libdns，如此处所述 http://www.ehow.com/how_4747553_fix-unknownhostexception-java-applications-ubuntu.html .完成此操作后，便可以使用jdk5和jdk6运行mvn.
Just to close the loop on this one - it turned out to be an issue with the libraries debian had available for java uses to resolve hostnames. The fix is to apply a new libdns for java as described here http://www.ehow.com/how_4747553_fix-unknownhostexception-java-applications-ubuntu.html. Once I did this I am able to run mvn with jdk5 and jdk6.
