Gradle home cannot be found on Mac

I've installed gradle on MAC using terminal.

brew install gradle

Gradle has been installed successfully.

gradle -v

OS:           Mac OS X 10.12.3 x86_64

but I can not find gradle home.

echo $GRADLE_HOME
[empty result]

the first step to determine home directory is detect location of gradle instruction:

which gradle
/usr/local/bin/gradle

there is incomprehensible bash file.

Any ideas how to detect gradle home directory via terminal?

You can use command:

brew info gradle

As the result you will have something like this:

gradle: stable 4.0.1
Build system based on the Groovy language
https://www.gradle.org/
/usr/local/Cellar/gradle/3.4 (181 files, 74.5MB) *

--with-all
	Installs Javadoc, examples, and source in addition to the binaries

Here, on the line 4 you can see the home path : /usr/local/Cellar/gradle/3.4

You can retrieve the path for GRADLE_HOME automatically using the following snippet in your .bashrc or .zshrc:

export GRADLE_HOME=$(brew info gradle | grep /usr/local/Cellar/gradle | awk '{print $1}')

This is handy when the path to Gradle's home changes, when Gradle is updated.

On Mojave (v10.14), Gradle v5.4, I had to append libexec after Gradle version for IntelliJ to work.

/usr/local/Cellar/gradle/5.4/libexec

I've gradle installed When using homebrew, below one failed with me, and kept telling undefined:

/usr/local/Cellar/gradle/<version>

The below symlink worked perfectly, and solved my issue:

/usr/local/opt/gradle/libexec

"brew info gradle" command not always give the installed path

br*ew info gradle

On Mojave, Gradle v6.6, I appended libexec after Gradle version for IntelliJ to work.

/usr/local/Cellar/gradle/5.4/libexec

My point isn't enough for commenting on flic's answer in the previous post. If it happens to be in MacOS, the asterisk should be escaped as:

brew info gradle | sed -nE 's#^(/usr/local/Cellar/gradle/[^ ]+).+\*#\1#p'

or there will be sed: 1: "s#^(/usr/local/Cellar/g ...: RE error: repetition-operator operand invalid" error reported.
