“Type interface is not known to the MapperRegistry” exception using mybatis

Question

I\'m setting up mybatis using annotations, and getting this helpful exception

org.apache.ibatis.binding.BindingException: Type interface org.foo.Bar is

Answer 1

Happened to me when creating a shadowJar/bootJar for a spring boot project and using org.springframework.boot gradle plugin

When the jars are zipped inside the bootJar myBatis may fail to find the XML configuration files and will throw the described exception

adding this block in the build.gradle file:

bootJar {
    requiresUnpack '**/MyProblematic.jar'
}

solved my problem
