> Using the Gradle Build System with Spring Boot

> What is Gradle?

• A software build system; Analogous to Maven
• Modular to the core
• Highly extensible
• Robust multi-project support
• Rich dependency managment,; transitive, exclusions, etc.
• Groovy language

> How to Install Gradle

• https://docs.gradle.org and select "User Guide" from the top toolbar. See the section titled: "Installing Gradle"

• GRADLE_HOME 환경변수 추가
• PATH 에 %GRADLE_HOME%/bin 추가
• java version은 기본적으로 JAVA_HOME 환경변수의 것으로 사용된다.
• 별도 java version을 지정하고 싶으면 %GRADLE_HOME%/bin/gradle.bat 에 JAVA_HOME 설정 추가

ex) set JAVA_HOME=C:\eGovFrame-3.5.1\bin\jdk1.8.0_45

• > gradle -v 명령으로 환경설정 확인

> gradle wrapper --gradle-version 2.10

위 명령을 실행하면 project directory 내 아래 파일들 생성됨

> 최초 build

> gradlew assemble

* 위 명령어를 실행하면 필요한 jar 파일 다운로드 및 소스 compile, application jar파일 생성

* 아래 그림처럼 build 디렉토리 생성

> clean

> gradlew clean

* build 디렉토리 삭제

> 이후 수정 후 build 시마다

> gradlew clean assemble

> unit test

> gradlew clean check

* 위 명령 결과 아래과 같이 build/reports, build/test-results 가 생기고, reposrt/index.html에서 unit test 결과를 조회할 수 있다.

> compile and test 동시 수행

> gradlew clean build

> boot application 실행

> gradlew clean bootRun
