Installation
Gradle runs on all major operating systems and requires only a Java JDK or JRE version 7 or higher to be installed. To check, run java -version:
$ java -version java version "1.8.0_121"
Step 1. Download the latest Gradle distribution
download url : https://gradle.org/releases/
提供了二进制包和完整包（包含User Manual、API Javadoc、DSL Reference）
Step 2. Unpack the distribution
Create a new directory C:\Gradle with File Explorer.
Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder gradle-4.1 to your newly created C:\Gradle folder.
Alternatively（另外） you can unpack the Gradle distribution ZIP into C:\Gradle using an archiver tool of your choice.
Step 3. Configure your system environment
In File Explorer right-click on the This PC (or Computer) icon, then click Properties -> Advanced System Settings -> Environmental Variables.
Under System Variables select Path, then click Edit. Add an entry for C:\Gradle\gradle-4.1\bin. Click OK to save.
Step 4. Verify your installation
Open Windows command prompt and run gradle -v to run gradle and display the version,
e.g.:
$ gradle -v Gradle 4.1
