已采纳

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

Can you understand Chinese? 你解决了这个问题吗？或许你说的对，但我没有其它的配置文件可供参考你有正确的mybatis-generator.xml文件吗？

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

题主是mybatis-generator.xml中jdbcConnerctior的连接驱动配置错了，你看看你的是不是也是这个问题
