Infinite "Refreshing <project_name> SBT project"

I'm trying to import quite large project in Intellij IDEA. I left "Use SBT shell" checked before importing and now I see "Refreshing 'main' SBT project" for about 4-5 hours and SBT shell is in "initializing" status. What can I do with it, how is it possible to finally import the project? What can be the issue?

I have only 4Gb RAM on my laptop and I gave 2 of them for SBT, but I don't think it's so crucial

My IDEA version is 2017.2.5, SBT version is 0.13.9
