带有Maven的Spring-Boot外部lib文件夹

Question

我需要外部化应用程序的依赖关系。我想为我的Spring Boot应用程序实现以下布局

.
├── *.properties
├── static
├── main.jar
└── lib
     └── *.jar

lib文件夹中包含我的依赖项。

我尝试使用maven-jar-plugin和spring-boot-maven-plugin，但出现以下错误：

Could not find or load main class com.Application

我已经阅读了几天，但已经丢弃：

• 使用spring-boot-thin-layout
• 创建远端jar：这是项目要求。
