通常这应该可以正常工作

Answer 1

由于Spring Boot 2.1.5已将maven-jar-plugin升级到3.1.2，这是与Spring Boot 2.1.5一起使用时的最新惊喜Eclipse bug

解决方法是通过将以下内容添加到pom.xml中来将其降级到以前的版本：

<properties>
    <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

Answer 2

    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
