Wrapper
Look in the root of the project for a gradlew file. If it exists, you can use the Gradle wrapper to execute the build without installing Gradle. Learn how to use it here. If you want information on how it’s generated in the first place, check out the user guide.
If that file doesn’t exist, you’ll need to install Gradle. The user guide explains how to do this generically for all platforms.
That’s not the only way you can install Gradle, though, the following links provide alternative approaches:
