如何使用 Spring Boot Loader 为 SpringBoot 应用程序生成可执行 jar

Question

我们如何在以下结构中为 SpringBoot 应用程序生成可执行 jar

example.jar
 |
 +-META-INF
 |  +-maven
 |  +-MANIFEST.MF
 +-org
 |  +-springframework
 |     +-boot
 |        +-loader
 |           +-<spring boot loader classes>
 +-BOOT-INF
    +-classes
    |  +-com
    |     +-mycompany
    |        +-project
    |           +-YourClasses.class
    +-lib
    |  +-dependency1.jar
    |  +-dependency2.jar

以上是我的应用程序的

pom.xml

，它被配置为生成jar文件。 目前，当我执行 mvn clean package 时，正在生成 jar 但不是可执行文件。

期望： 依赖项应放在嵌套的 BOOT-INF/lib 目录中。
