boot.springBootPlugin行引用了父项目的 build.gradle文件中定义的 boot数组的 springBootPlugin属性。该文件的 内容片段(仅与 SpringBoot相关的配置)如下所示:

ext{
...
bootVersion = '2.0.6.RELEASE'
...
boot = [
springBootPlugin: "org.springframework.boot:spring-boot-gradle-plugin:$bootVersion",
starter:"org.springframework.boot:spring-boot-starter:$bootVersion",
...     
}

public class HelloWorld {

    private static Logger logger = LoggerFactory.getLogger(HelloWorld.class);
