The problem of importing local jar packages that springboot child module depends on

problem description

A spring boot project recently built by the company is implemented using multi-module. When the entry module is finally packaged, the local jar that the sub-module depends on can never be imported into BOOT-INF/lib. Many methods have been found on the Internet, all of which are imported by putting the local jar package in the lib in the startup module, which is not applicable to this project

the environmental background of the problems and what methods you have tried

entry module configuration < includeSystemScope > true < / includeSystemScope > invalid
