APPLICATION FAILED TO START

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.baomidou.mybatisplus.core.MybatisMapperAnnotationBuilder.getLanguageDriver(MybatisMapperAnnotationBuilder.java:386)

The following method did not exist:

    org.apache.ibatis.session.Configuration.getLanguageDriver(Ljava/lang/Class;)Lorg/apache/ibatis/scripting/LanguageDriver;

The method's class, org.apache.ibatis.session.Configuration, is available from the following locations:

    jar:file:/C:/Users/Gavin/.m2/repository/org/mybatis/mybatis/3.5.0/mybatis-3.5.0.jar!/org/apache/ibatis/session/Configuration.class

The class hierarchy was loaded from the following locations:

    org.apache.ibatis.session.Configuration: file:/C:/Users/Gavin/.m2/repository/org/mybatis/mybatis/3.5.0/mybatis-3.5.0.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.apache.ibatis.session.Configuration


Process finished with exit code 0

报错原因：Maven引入冲突导致（项目中引入Activiti和Mybatis-plus，两个包都包含mybatis）

解决方案：排除其中一个包中mybatis
