Some suggestions for reference only:

• Rename dubbo-spring-boot-project to dubbo-spring-boot-all
• Move dubbo-spring-boot-compatible/dubbo-spring-boot-autoconfigure-compatible to dubbo-spring-boot-1-autoconfigure

Some suggestions for reference only:

• Rename dubbo-spring-boot-project to dubbo-spring-boot-all
• Move dubbo-spring-boot-compatible/dubbo-spring-boot-autoconfigure-compatible to dubbo-spring-boot-1-autoconfigure
• Move dubbo-spring-boot-compatible/dubbo-spring-boot-actuator-autoconfigure-compatible to dubbo-spring-boot-1-actuator-autoconfigure

dubbo-spring-boot-all strikes me as fatjar, but for now, it's just a directory of files, so I think dubbo-spring-boot-project is more appropriate

dubbo-spring-boot-compatible also needs to exist because it is managed as a 1.x bom, otherwise, it cannot override the parent's high version dependencies.
