使用公共库的微服务出错,找不到共享库的pom和jar

我正在构建这个由几个微服务组成的应用程序,使用公共类和可重用类,所有这些类都共享在一个名为commons的包中,同时在每个微服务上导入,以使用任何cladsses公共共享的东西。出于某种原因,需要一个微服务(微管道)来生成一个新的jar,但是在这个过程中,我得到了一个警告:首先在pom中找不到公共库,其次,抛出了一个错误,所有这些都是我在docker映像上部署每个微的。
我的工作sapce结构包含所有组件,包括公共和所有其他微服务,如下所示:

假设我的公共库设计如下:

由于可共享资源的ist功能而禁用其主类:

package com.commons;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class CommonsApplication {
}

然后在我的一个微服务(microproducts)上,我首先在pom上导入公共库,然后在它的主类中扫描所有组件、实体、基类所需的包,这些包来自公共以便工作

如您所见,公共库作为第一个导入
然后主类的设计是这样的:

package com.microproducts;

import com.microproducts.repositories.ImgSubTypeRepository;
import com.microproducts.repositories.ProductRepository;
import com.microproducts.repositories.RenterRepository;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@EnableEurekaClient
@SpringBootApplication
@ComponentScan({"com.commons.dtos","com.commons.exceptions","com.commons.responses","com.commons.repositories","com.commons.responses"})
@EntityScan("com.commons.entities")
@ComponentScan(basePackageClasses = {ProductRepository.class, RenterRepository.class, ImgSubTypeRepository.class})
public class MicroproductsApplication  {
    public static void main(String[] args) {
        SpringApplication.run(MicroproductsApplication.class, args);
    }
}

你知道为什么这个行为不让我构建一个jar,因为没有“找到”我以前导入的公共jar吗?

正如khbmarbaise所说:
如果你使用 spring-boot-starter-parent 作为父级,模块/项目不能用作依赖项。

那么,删除.m2存储库,重建所有项目(包括公共项目)就可以了
