I found the solution :-) What you need to do is specify the http proxy in the maven settings.xml.
Besides *HTTP *we need to set the *HTTPS *proxy to be able to download artifacts from https://m2proxy.atlassian.com. To be able to do so you need to pass the https settings to the MAVEN_OPTS in Jenkins like this: *-Dhttps.proxyHost=<proxyHost> -Dhttps.proxyPort=<proxyPort> -Dhttps.proxyUser=<proxyUser> -Dhttps.proxyPassword=<proxyPassword>* Then it works fine! If your proxy doesn't require authentication, don't include the -Dhttps.proxyUser and -Dhttps.proxyPassword. -- View this message in context: http://jenkins.361315.n4.nabble.com/Maven-does-not-read-nexus-settings-from-settings-xml-java-net-UnknownHostException-m2proxy-atlassian-tp4662970p4664069.html Sent from the Jenkins issues mailing list archive at Nabble.com. -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
