How to use an existing Gradle project in IntelliJ IDEA 13/14

Question

I am using Gradle and IntelliJ IDEA. Normally I use apply plugin: 'idea' to generate the IDEA project files. With IDEA 12 I was used to work with the JetGradle tool view.

Now I updated to IDEA 13 and the JetGradle tool view is gone. When I use the old run configuration gradle:run, IDEA tells me:

Error running gradle:run:
Module 'X' is not backed by gradle.

How can I activate the gradle build in IDEA 13 without the tool view? I found this tweet from Cédric Champeau, but was still not able to solve it. Do I have to turn my simple gradle project into a multi module project or what?

Update
With File - Import Project ... I can import the build.gradle file and than I can choose View - Tool Windows - Gradle, which was hidden before. Is this the way to go?
