一、build.gradle

dependencies {
        // src/main
        compileOnly 'org.projectlombok:lombok'
        annotationProcessor 'org.projectlombok:lombok'

        // src/test
        testCompileOnly 'org.projectlombok:lombok'
        testAnnotationProcessor 'org.projectlombok:lombok'
}

注意：如果不添加 testAnnotationProcessor 'org.projectlombok:lombok'，那么单元测试编译过程中会报错👇

error: cannot find symbol
        log.info("hello");
        ^
  symbol:   variable log

二、下载 Lombok Plugin
