Building Spring Boot 2 Applications with Gradle
The Spring Boot team provides a great getting started guide, which includes instructions for using Gradle as the build tool. In addition, you can find the most up-to-date information for using the Spring Boot Gradle plugin in their documentation.
The guide that used to exist here was not up-to-date with the latest Spring Boot version and Gradle plugin features. This is why it now references the guide provided by the Spring Boot team.
