IntelliJ IDEA 15无法导入Maven项目

Question

Here are some of the messages from my IDEA log file. It appears that it is not able to connect to some maven service on localhost. This used to work just fine for me with 14.

Update - 1

Found this bug report -> https://youtrack.jetbrains.com/issue/IDEA-147234 which says we should upgrade maven to atleast 3.3.3 I did but I am still seeing the same problem

Answer 1

Looks like it's related with /etc/hosts as @MoizRaja mentioned. I suggest to try commenting everything in /etc/hosts and just leave

127.0.0.1       localhost
