We don’t need to perform any installations to use Gradle in our Spring Boot project since we are utilizing the Gradle wrapper within our project.
The Gradle configuration is done in the project’s
build.gradle file. The file can be customized to fit the specific needs of the project and can be used to automate tasks such as building, testing, and deploying the software. The
build.gradle file is an important part of the Gradle build system and is used to configure and manage the build process for a software project. The
build.gradle file typically includes information about the project’s dependencies, like external libraries and frameworks that are needed for the project to compile. You can use either the Kotlin or Groovy programming languages to write
build.gradle files. In this book, we are using Groovy. The following is one example of a Spring Boot project’s
id 'org.springframework.boot' version '3.1.0'
id 'io.spring.dependency-management' version '1.1.0'
group = 'com.packt'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
build.gradle file typically contains the following parts:
- Plugins: The
pluginsblock defines the Gradle plugins that are used in the project. In this block, we can define the version of Spring Boot.
- Repositories: The
repositoriesblock defines the dependency repositories that are used to resolve dependencies. We are using the Maven Central repository, from which Gradle pulls the dependencies.
- Dependencies: The
dependenciesblock specifies the dependencies that are used in the project.
- Tasks: The
tasksblock defines the tasks that are part of the build process, such as testing.
Gradle is often used from the command line, but we are using the Gradle wrapper and Eclipse, which handles all the Gradle operations we need. The wrapper is a script that invokes a declared version of Gradle, and it standardizes your project to a given Gradle version. Therefore, we are not focusing on Gradle command-line usage here. The most important thing is to understand the structure of the
build.gradle file and how to add new dependencies to it. We will learn how to add dependencies using Spring Initializr in the next section. Later in this book, we will also add new dependencies manually to the
In the next section, we will create our first Spring Boot project and see how we can run it using the Eclipse IDE.
