How to define Gradle's home in IDEA?

问题:

I am trying to import a Gradle project into IntelliJ, and when I get to the Gradle Home textbox, it is not automatically populated, nor will typing in the path of Gradle Home result in a valid location - I have the GRADLE_USER_HOME environment variable set (to what I think is!) the correct path, and I have been able to successfully import this same project into Eclipse. Any suggestions?

回答1:

You can write a simple gradle script to print your GRADLE_HOME directory.

task getHomeDir {
    doLast {
        println gradle.gradleHomeDir
    }
}

and name it build.gradle.

Then run it with:

gradle getHomeDir

If you installed with homebrew, use brew info gradle to find the base path (i.e. /usr/local/Cellar/gradle/1.10/), and just append libexec.

回答2:

Installed on a Mac via Homebrew, the path

/usr/local/opt/gradle/libexec

is preferable to

/usr/local/Cellar/gradle/X.X/libexec

since the former will survive version upgrades.

回答3:

If you installed gradle with homebrew, then the path is:

/usr/local/Cellar/gradle/X.X/libexec

Where X.X is the version of gradle (currently 2.1)

回答4:

If you are using IntelliJ, just do the following.

1. Close the project
2. (re)Open the project
3. you will see "Import gradle project" message on the right bottom. click.
4. select "Use default gradle wrapper". not "Use local gradle distribution"

That's all.

This is what helped me solve the problem of not having Gradle home set for the IDEA when importing a Gradle project.

THREE OPTIONS -- (A) Default Wrapper (B) "gradle 'wrapper' task configuration" OR (C) "local gradle distribution" defined by jetbrains: https://www.jetbrains.com/help/idea/gradle-settings.html

A. Default Wrapper (recommended)

If you are able, select this recommended option. If it is grayed out, see option C, which should then set your default for all subsequent projects.

B. Gradle 'Wrapper' Task Configuration

If you want IDEA to define your gradle version for you from your build script

1. Set this option if you define your gradle build versions as a task within your actual gradle build.

Example below from jetbrains: https://www.jetbrains.com/help/idea/gradle-settings.html

(useful if you do not want to share gradle builds between projects)

C. Local Gradle Distribution

1. Run the following command to get gradle location:

   brew info gradle (if gradle was installed with homebrew)


2. You are looking for something like this:

   /usr/local/Cellar/gradle/4.8.1


3. Next, append 'libexec' to the gradle location you just found:

/usr/local/Cellar/gradle/4.8.1/libexec

This is because "libexec is to be used by other daemons and system utilities executed by other programs" (i.e. IDEA). Please see https://unix.stackexchange.com/questions/312146/what-is-the-purpose-of-usr-libexec

4. Finally, put that new path in the Gradle home input box if IDEA prompts you.

5. IDEA should now have allowed you to hit OK

回答6:

On a mac it should ideally be at : /Applications/Android Studio.app/Contents/gradle/gradle-2.14.1

(Replace the version string with the latest)

回答7:

This is instruction for MAC only. I had the same problem. I solved it by configuring $GRADLE_HOME in .bash_profile. Here's how you do it:

• Open .bash_profile (usually it's located in the user’s home directory).
• Add the following lines to update $PATH variable: export GRADLE_HOME=/usr/local/opt/gradle/libexec export PATH=$GRADLE_HOME/bin:$PATH
• Save it.
• Apply your changes by running source .bash_profile

I wrote my own article with instruction in a case if somebody will encounter the same problem.

回答8:

AFAIK it is GRADLE_HOME not GRADLE_USER_HOME (see gradle installation http://www.gradle.org/installation).

On the other hand I played a bit with Gradle support in Idea 13 Cardea and I think the gradle home is not automatically discover by Idea. If so you can file a issue in youtrack.

Also, if you use gradle 1.6+ you can use the Graldle support for setting the build and wrapper. I think idea automatically discover the wrapper based gradle project.

$ gradle setupBuild --type java-library

$ gradle wrapper

Note: Supported library types: basic, maven, java

C:\Users\<_username>\.gradle\wrapper\dists\gradle-3.3-all\55gk2rcmfc6p2dg9u9ohc3hw9\gradle-3.3

\Android studio\gradle didn't worked for me.

And "Default gradle wrapper" wasn't configured while importing (cloning) the project from bitbucket

回答10:

If you're using MacPorts, the path is

/opt/local/share/java/gradle

回答11:

I had some weird errors where it could not find my class, I had to right click on my src folder (was red) to "Make Directory as" -> Source Folder Root

回答12:

In case you are using Mac, most probably your gradle home should be /usr/local/gradle-2.0 for example.

In preference of IDEA search for gradle and set gradle home as given above. It should work

回答13:

Click New -> Project from existing sources -> Import gradle project...

Then Idea recognized gradle automatically.
