Best way to add Gradle support to IntelliJ Project
JavaGitIntellij IdeaGradleJava Problem Overview
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 the .ipr file as we have a few build configurations that we track. We will be getting rid of those in favor of Gradle eventually but I can't screw things up too much until the Gradle conversion is done.
Also, our Java source files are located in the root of the src directory instead of src/main/java as is standard.
Is there a way I can add Gradle to my project that won't make me delete and recreate my IntelliJ project and won't screw everyone else up when they do a Git pull?
Java Solutions
Solution 1 - Java
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
Solution 2 - Java
There is no need to remove any .iml
files. Follow this:
- close the project
File
->
Open...
and choose your newly createdbuild.gradle
- IntelliJ will ask you whether you want:
Open Existing Project
Delete Existing Project and Import
- Choose the second option and you are done
Solution 3 - Java
Another way, simpler.
Add your
build.gradle
file to the root of your project. Close the project. Manually remove "*.iml" file and/or ".idea" directory. Then choose "Import Project...", navigate to your project directory, select the build.gradle file and click OK.
Solution 4 - Java
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.
Solution 5 - Java
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.

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.
Solution 7 - Java
-
Add
build.gradle
in your project's root directory. -
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'
Solution 8 - Java
To add to other answers. For me it was helpful to delete .mvn
directory and then add build.gradle
. New versions of IntelliJ will then automatically notice that you use Gradle.
