你应该可以在C:\Program Files\Android\Android Studio\Gradle\Gradle 2.2.1中找到它。这是运行Windows 7 64位。Android Studio 1.0.2。

在Linux Mint 17上是这样的

/usr/share/gradle

对我来说

在Linux上运行:whereis gradle。

对我来说是/usr/lib/gradle/1.10。

Mac OSX / Linux

Step 1: Open terminal :)
Step 2: Open .bash_profile in vim to edit: 
        > vi ~/.bash_profile 
Step 3: Add line: 
        > export GRADLE_HOME=/usr/local/opt/gradle 
        (for me it was this location, it can be different for u)
Step 4: Add line: 
        > export PATH="$PATH:$GRADLE_HOME/bin" 
        (to export bin directory of gradle)
Step 5: Verify by reopening the terminal or new tab, and check by echoing: 
        > echo $GRADLE_HOME

下载Gradle http://www.gradle.org/downloads 安装 将Gradle home设置为安装目录

这是我在AndroidStudio/Idea for Mac上的解决方案

$ env | grep GRADLE
GRADLE_HOME=/usr/local/Cellar/gradle/2.6
GRADLE_USER_HOME=/Users/leon/.gradle
