[jira] [Commented] (MNG-5828) Artifact download loses proxy username during transfer, failing download

["John Elion (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-5828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14565829#comment-14565829 ] 

John Elion commented on MNG-5828:
---------------------------------

I have successfully worked around the issue by setting up a local Nexus server which forwards through our firewall to external repositories; such that all of Maven's requests are routed to a local "mirror".  Through Nexus , Maven seems to have successfully retrieved artifacts that had failed when Maven reached out directly to the internet through the firewall proxy.

> Executing 'mvn site' causes Maven to successfully download most artifacts, but several failures are reported with the message 
> [WARNING] Could not transfer metadata org.codehaus.mojo:findbugs-maven-plugin/maven-metadata.xml from/to central (https://repo.maven.apache.org/maven2): Error transferring file: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 authenticationrequired" from https://repo.maven.apache.org/maven2/org/codehaus/mojo/findbugs-maven-plugin/maven-metadata.xml with proxyInfo ProxyInfo{host='mamwg.gdc4s.com', userName='null', port=8080, type='https', nonProxyHosts='null'}
> The proxy configuration does specify a username, and a "mvn -X" log shows Maven to be aware of the username a few lines earlier.
> [DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for https://repo.maven.apache.org/maven2 via mamwg.gdc4s.com:8080 with username=p58042, password=***
> I don't see a way to attach, but if I can do so after saving I will attach a fairly simple pom file, settings.xml (stripped of passwords), and plain and debug log files that will reproduce the error with the commands 'mvn -s settings.xml site' and 'mvn -X -s settings.xml site'.
> I have listed this as "minor" because my end build results thus far have been successful and the components which have failed to download have apparently not impacted my building or testing - in some cases it appears the component is already downloaded to my local repository; however, there are hundreds of these warnings in my build logs.
