Java Project Requirements

• complie Java classes from .java into .classes files
• manage resources that live alongside code
• package everything into a jar file
• easily run tests
• define dependencies

Note

All you have to do is add Gradle Java Plugin

plugins {
    id 'java'
}

1. 컴파일 자바

• adds a tasks compileJava
  • ./gradlew compileJava
• uses Java installation to compile .java into .class files
• output .class files to build directory

2. 리소스 처리

• adds a tasks processResources
  • ./gradlew processResources
• copies contents of resources directories into build directory

3. 패키징

• adds a tasks jar
  • ./gradlew jar
• adds compiled classes and resources to jar archive
• jar file 이름 - <project-name>-<version>.jar

4. 테스트

• adds a tasks test
  • ./gradlew test
• compiles test, processes resources, runs tests
• also creates a test report

5. 의존성 관리

• use the dependencies section of build.gradle

build.gradle#dependencies

dependencies {
    implementation 'org.apache.commons:commons-lang3:3.11'
}
