Maven打包成jar时出了很多问题。Missing artifact?报错

    我在做的是一个游戏项目：暂时有两个工程，一个是gameCommon  放一些每个工程都会运用到的常量和服务器配置文件，没有引用到任何的jar包。 第二个是游戏主项目，引用了各种开猿jar包。我该如何编写pom文件才能使工程正常打出jar呢？ 

这是common的pom：<parent>报错啊，说什么Missing artifact 缺父类导入的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<artifactId>GameCommon</artifactId>
	<parent>
	    <groupId>com.oasgames.dota</groupId>
	    <artifactId>GameServer</artifactId>
	    <version>0.0.1-SNAPSHOT</version>
	    <relativePath>../GameServer</relativePath>
  	</parent>
</project>

这是主模块的pom
