一、运行环境

spring-boot版本2.3.0

The POM for org.mybatis.spring.boot:mybatis-spring-boot-starter:jar:1.3.0 is invalid, transitive dependencies (if any) will not be available: 1 problem was encountered while

building the effective model for org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.0

   org.springframework.boot   spring-boot-starter-parent   2.3.0.RELEASE

mybatis的版本1.3.0

   org.mybatis.spring.boot   mybatis-spring-boot-starter   1.3.0   true

二、问题排查

从git上拉下来的代码，刚开始是MyBatisConfigurer配置类的两个包导不进来

import org.apache.ibatis.session.sqlSessionFactory;import org.mybatis.spring.SqlSessionFactoryBean;

所以将问题定位在mybatis-spring-boot-starter的包上，怀疑是包损坏了，删除包之后重新下载，仍出现上述情况。排除jar损坏的原因。

后来刷新Maven仓库时报了下面的警告

[WARNING]The POM org.mybatis.spring.boot:mybatis-spring-boot-starter:jar:1.3.0 for is invalid, transitive dependencies (if any) will not be available

随后我就去csdn上查找解决方案，都没有很好的得到解决

最后看到了“兵工厂三剑客”这位博主的博客按着他的处理问题的流程，通过打印maven的日志信息

打印日志指令如下：

 mvn -X -U clean package

查看日志发现下面报错信息

[WARNING] The POM for org.mybatis.spring.boot:mybatis-spring-boot-starter:jar:1.3.0 is invalid, transitive dependencies (if any) will not be available: 1 problem was encountered while building the effective model for org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.0[FATAL] Non-parseable POM E:\MavenRepository\org\mybatis\mybatis-parent\28\mybatis-parent-28.pom: processing instruction can not have PITarget with reserved xml name (position: END_TAG seen ...\r\n\r\n\r\n
