  • Are you trying this from behind a firewall? Check that nothing is blocking your traffic to repo.maven.apache.org – randal4 Aug 21 '18 at 15:59
  • Yes I am behind a firewall and have added PROXY in IntelliJ IDEA which when tested thru the , shows its successful. I get this error for each Dependency in MAVEN POM.xml file: FAILED TO READ ARTIFACT DESCRIPTOR – Voila Aug 21 '18 at 16:16
  • Do you have your proxy setup for http AND https? How are you testing the connection? – randal4 Aug 21 '18 at 16:17
  • In INTELLIJ IDEA --> Settings --> HTTP PROXY, I have selected - Manual Proxy Configuration - HTTP (NOT SOCKS) – Voila Aug 21 '18 at 16:19
  • Take a step back and try `ping repo.maven.apache.org` and see if you get a response. If not, setup proxy settings in your machine. If your workplace gives an autoproxy use that. – Bajal Aug 21 '18 at 17:21
  • For Eclipse and the MVN command line see https://stackoverflow.com/q/7737710 – howlger Aug 21 '18 at 19:41
  • IntelliJ is fixed... I created and added Proxy information to it. Thats all, the dependencies kept flowing in. @howlger, will check the post you mentioned. Thanks all. – Voila Aug 21 '18 at 20:41
