在控制台上maven打包报错。

Question

楼主刚看徐晓斌的《maven实战》，正在控制台上鼓捣maven呢，mvn clean compile,mvn clean test也成功，然后mvn clean package打包也成功，但是由于打出来的Jar包没有指定main方法的位置，我就按照书上的案例，加入maven-shade-plugin插件，在pom.xml加入这话话，一直打包都是错误的。
pom.xml文件配置如下:

<?xml version="1.0" encoding="UTF-8"?>

          </execution>
        </executions>
      </plugin>
    </plugins>
  </build> 
</project>

控制台报错信息如下：

里面居然是2.3.2版本，我的本地仓库下载下载下来的不是指定的那个1.2.1版本，这是怎么回事?
