如果你使用MacPorts gradle的主页是:

/opt/local/share/java/gradle

在Windows上

C: / Android工作室/ jre

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

在Windows中

..\AndroidStudio2.0Beta6\android-studio\gradle\gradle-2.10

我必须用这个

“C:\Program Files\Android\Android Studio\gradle\gradle-4.1”
