Say hello to the fresh IntelliJ IDEA 2016.3 EAP build, which brings several new features worth checking out.
Support for Polyglot Maven
First of all, we've added the support for Polyglot Maven. In case you don't know, this is a set of Maven extensions that allows the POM file to be written in Groovy, Scala, Ruby and other languages.
While project import works for any language, coding assistance within POM files is available only for Groovy.
Apart from that you can work with the projects that use Polyglot Maven just as with any other Maven projects.
