I have Intellij IDEA Community 2017.3 installed on a Linux distrib and I need to use an authenticated proxy to get to the Internet. I have a system-wide proxy , and I have configured the IntelliJ proxy and the maven jvm proxy as explained in Intellij Community can't use http proxy for Maven. Maven projects work well (I can get archives on the Internet), and I can get the list of plugins.
When I try to import libraries from maven (under Project structure > Libraries > + > from Maven) or when I test the Artifactory or Nexus Service URLs under Settings > Build, Execution, Deployment > Remote Jar Repositories, I cannot get any new library and tests of default urls returns "no reporitories found". In the idea logs, I get a 407 error:
2018-01-24 13:37:43,178 [ 284705] INFO - MavenRepositoryServicesManager - java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 407 Proxy Authentication Required"

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 407 Proxy Authentication Required"
Note that I have also configured the settings.xml file in the .m2 directory, and tested it outside IntelliJ. It also works fine.
I suppose there is another place where I should indicate proxy info, but I don't know where. My proxy requires user name and password.
