I have looked around quite a bit and haven\'t found the best solution to convert an existing IntelliJ project to Gradle. I work in a team environment and we currently share
In IntelliJ 2017.2.4 I just closed the project and reopened it and I got a dialog asking me if I wanted to link with build.gradle which opened up the import dialog for Gradle projects.
No need to delete any files or add the idea plugin to build.gradle.
