Setting up Spring Boot with Gradle

We have seen that Java 8 is the minimum requirement for Spring Boot 2.0, both with Maven and Gradle. However, if you want to use Gradle, then first install Gradle 4 or above in your machine from www.gradle.org/.

Now, see the following Gradle Spring Boot dependencies file with org.springframework.boot groupId. Here's what the build.gradle file should look like:

buildscript {
   repositories {
         jcenter()
         maven { url 'http://repo.spring.io/snapshot' }
         maven { url 'http://repo.spring.io/milestone' }
   }
   dependencies {
         classpath 'org.springframework.boot:spring-boot-gradle-plugin:2.0.0.M7'
   }
}
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

jar {
   baseName = 'HelloWorld'
   version =  '0.0.1-SNAPSHOT'
}

repositories {
   jcenter()
   maven { url "http://repo.spring.io/snapshot" }
   maven { url "http://repo.spring.io/milestone" }
}

dependencies {
   compile("org.springframework.boot:spring-boot-starter-web")
   testCompile("org.springframework.boot:spring-boot-starter-test")
}
 

The preceding Gradle file has minimum requirements for the Spring Boot application. You could use either Maven or Gradle since the process is the same. Spring Boot creates an application using the same process.

Let's create your first Spring Boot application and see how to set up the project's structure using Spring Boot Initializr.
