Maven import in Intellij IDEA runs out of memory on a large project -


import of maven project ends with

exception java.lang.outofmemoryerror: gc overhead limit exceeded
  1. i've tried define environment variable: maven_opts = -xmx1g.
  2. i've tried add -xmx1g maven vm options via settings -> build tools -> maven -> runner.

without success. else can do?

the solution set -xmx1g (or more) in maven vm options importer (yes, separate option!). go "settings -> build tools -> maven -> importing", , find option there.
