Spring Boot Gradle with Eclipse

I would like to use gradle and eclipse to develop Spring Boot Application
This is to make development environment.
The goal is to create program on Eclipse and debug as Spring Boot Application

IDE : Spring Tool Suite
Gradle : Gradle 2.9
OS : Mac OS X EI Capitan

Steps

1. Install STS
2. Install gradle in Mac
3. Install Gradle IDE plugin in Eclipse
4. Create build.gradle
5. Create eclipse project and import
6. Debug setting

Install Gradle

In Mac OS X, brew is the simplest way.

brew install gradle

Install Gradle IDE plugin in Eclipse

From Eclipse Market Place “Help” -> “Eclipse marketplace”
Search by Gradle, you can see Gradle IDE plugin

Create build.gradle

Prepare project root directory and create build.gradle on this project root.

mkdir BootSample
cd BootSample

build.gradle

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.0.RELEASE")
  }
}

apply plugin: "java"
apply plugin: "spring-boot"
apply plugin: "eclipse"

eclipse {
  classpath {
    containers "org.springsource.ide.eclipse.gradle.classpathcontainer"
  }
}

jar {
  baseName = "BootSample"
  version =  "0.0.1-SNAPSHOT"
}

repositories {
  mavenCentral()
}

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

Create main source directory and project

mkdir -p src/main/java
mkdir -p src/test/java
gradle eclipse

Project files are done.

Import

You can import this project into Eclipse using “Existing Project”

After importing, “Project right click” -> “Configure” -> “Convert to Gradle Project”

Build

Run following command on your project root

gradle build

Debug from Eclipse

“Run” -> “Debug Configuration” -> Spring Boot App
Set Project, Main type
