Various examples of using Gradle
You can go to https://docs.gradle.org/ of course but I prefer a single all-in-one guide:
Most of the time you can use the gradlew or gradlew.bat script and no installation is necessary.
If you would like to install it, using Homebrew or Chocolatey is the easiest
brew install gradle
choco install gradle
gradle init --dsl kotlin
gradle init --dsl groovy
gradle wrapper
