我有一个多模块Maven项目，其结构如下：

- backend
  - service
    + product
      pom.xml
    pom.xml
  - docker
    pom.xml
  pom.xml

后端是主要的父级，具有两个以下子模块：service和docker。服务本身具有子模块产品。以下是相应的pom.xml文件：

  

后端的Pom.xml：

用于服务的Pom.xml：

    </resources>

</project>

我要做的是在模块docker中，我尝试重用product模块中的类，但不要重用GetProduct.java类。所以我在docker模块的Application类中定义了：

package com.tsoc.docker;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = {"com.tsoc.product"},
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = com.tsoc.product.api.rest.GetProduct.class)})
public class Application {
    public Application() {}

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

当我尝试在IDE下运行该程序时，它正常工作而没有错误。但是，当我尝试使用mvn clean compile进行编译时，maven抛出了一个错误：

  

java：包com.tsoc.product.api.rest不存在

我已经在docker模块的pom.xml中定义了对product模块的依赖关系，所以我认为它应该在这里工作，但没有。谁能帮我弄清楚我在这里犯了什么错误？

谢谢你！
