  1、git clone https://github.com/mfriedenhagen/dummy-lifecycle-mapping-plugin

  2、在拉下来的项目文件夹里mvn -Dmaven.test.skip -U clean install，这样就可以把lifecycle-mapping拉到本地maven仓库了

  3、重新run mybatis-generator.xml

  刚刚看到一个答案：（好像被删除了）

  git clone https://github.com/mfriedenhagen/dummy-lifecycle-mapping-plugin.git

  cd dummy-lifecycle-mapping-plugin/

  mvn -Dmaven.test.skip -U clean install

  
  

  大概就是上面3行指令结束后，重新run吧。

  Actually, the thing is we cannot directly use the mybatis-generator.xml downloaded online. We have to delete several lines in it and modify the directory, jdbc driver , user name and password exactly.  Sorry for my english, I don't have pinyin in library's computer

  问题的根本原因是不存在的插件 lifecycle-mapping

  无法从任何存储库org.eclipse.m2e下载工件：lifecycle-mapping：pom：1.0.0

  您的问题的解决方案是：m2e生命周期映射未找到

  - -虽然我还是没有解决

  感觉是没有吧mybatis-generator依赖进来，你把镜像换成阿里的，然后reimport一下maven试试欸
