然后我问了一些人，大多数人说插件版本是一个问题，或者找不到父项目(更新:pom,没有解决)

[PeneyLove]

打包为pom

[PeneyLove]

把本项目设置为父项目

在使用com.itfsw.mybatis.generator.plugins.ModelColumnPlugin插件后会报我之前的错，把这个插件注释掉则会有一个警告
[WARNING] itfsw:插件com.itfsw.mybatis.generator.plugins.SelectSelectivePlugin插件需配合com.itfsw.mybatis.generator.plugins.ModelColumnPlugin插件使用！ [WARNING] Plugin com.itfsw.mybatis.generator.plugins.SelectSelectivePlugin in context mysqlgenerator is invalid and will be ignored.
