Can't open maven projects and 'Unable to import maven project' error

Hello,

Please set maven output level to 'Debug' at File | Settings | Build, Execution, Deployment | Build Tools | Maven | Output level, configure Maven 3.3.3 or better, restart IDEA, reproduce the issue and provide new full idea.log file.

Hi,

Thanks for reply. I set maven output level to 'Debug'. And this is what came out. Maven version: 3.3.9

Hello,
I have the same issue with the latest release 2016.3.3 of IDEA downloaded today :-(
Are you using a nvidia graphics card? Because I saw a couple of issues about a potential conflict between its driver, as this one yesterday 115000077464. My nvidia driver release is the latest 378.49.

I accepted an upgrade of the nvidia driver (version 378.49 ; date : 24.01.2017) at the end of last week, when this issue appeared… So I have just downgraded the nvidia driver to the previous version (version 376.33 ; date : 14.12.2016) and it works fine now :-)

Nvidia Geforce 378.57 Hot Fix Drivers:

- Fixed crash in Minecraft and some other Java-based titles

http://www.guru3d.com/files-details/geforce-378-57-hotfix-driver-download.html

Upgrading nvidia driver actual worked! Thanks :-)

I have the same problem on my mac. I was able to import modules couple days. But now it stops working. 

this is logs for my last attempt:

It's not the same problem. Your problem is different and is probably caused by some invalid networking configuration/DNS issues.

You may have ESET Endpoint Security or similar tool installed which blocks all the connections on localhost. Please disable the antivirus/firewall and see if it helps.

Serge,

disabling ESET Network traffic filtering helped. But is there a solution to make it work without disabling antivirus features?

Normally antivirus/firewall should not block localhost connections. It's required for the IDE to work properly. It's either some misconfiguration of ESET or too strict policy that doesn't make sense.

Спасибо Сергей, вы очень помогли!
