idea的maven聚合项目的子项目编译时遇见Could not resolve dependencies for project，Could not find artifact异常

用idea自动生成的子项目依赖父项目的配置：

             <dependency>
            <groupId>xx.xxx.xxx</groupId>
            <artifactId>ego-project</artifactId>
            <version>1.0-SNAPSHOT</version>
             </dependency>

缺了一个配置

<dependency>
            <groupId>cn.gzsxt.ego</groupId>
            <artifactId>ego-project</artifactId>
            <version>1.0-SNAPSHOT</version>
            <type>pom</type>
    </dependency>
