Best way to add Gradle support to IntelliJ Project

Question

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

Answer 1

Add:

build.gradle 

in your root project folder, and use plugin for example:

apply plugin: 'idea'
//and standard one
apply plugin: 'java'

and with this fire from command line:

gradle cleanIdea 

and after that:

gradle idea

After that everything should work

Answer 2

Another way, simpler.

Add your

build.gradle

file to the root of your project. Close the project. Manually remove *.iml file. Then choose "Import Project...", navigate to your project directory, select the build.gradle file and click OK.

Answer 3

1. Add build.gradle in your project's root directory.

2. Then just File -> Invalidate Caches / Restart

Here is a basic build.gradle for Java projects:

plugins {
    id 'java'
}

sourceCompatibility = '1.8'
targetCompatibility = '1.8'
version = '1.2.1'

Answer 4

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.

Answer 5

Just as a future reference, if you already have a Maven project all you need to do is doing a gradle init in your project directory which will generates build.gradle and other dependencies, then do a gradle build in the same directory.

Answer 6

I'm using Version 12 of IntelliJ.

I solved a similar problem by creating an entirely new project and "Checking out from Version Control" Merging the two projects later was fairly easy.
