创建maven web项目出错Project build error: Non-parseable POM D:\Ieven\workspace\ws1802\jt-web\pom.xm

问题描述：创建分布式项目的子项目jt_web前台，添加父类项目依赖jt-parent，之后在pom.xml文件中添加tomcat插件，出现了如图二所示的错误。

Project build error: Non-parseable POM D:\Ieven\workspace\ws1802\jt-web\pom.xml: Duplicated tag: 'build' (position: START_TAG seen ...</dependencies>\r\n <build>... @23:10)

问题分析：在添加了父类项目依赖时，已经有了build关键字，之后添加tomcat插件，就会重复出现build关键字，只需要删除前一个build选项即可。修改后代如图四
