Intellij idea imported maven project, reported an error. BindingException - Codes Helper

for example, someone else created the project with eclipse, and then he gave me a zip package (everything was given to me, including cache and so on). I imported it with idea, and there was no problem with the test interface after the service.
here comes the key. He uploads the code of the project (not including the project cache) to SVN, and I down it down to the same configuration as before. org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.mal.mapper.TbVerificateMapper.selectByExample

67tbVerificateMapper.selectByExample

was wrong when testing the same interface! After comparison, I found that there is no problem with the project I install will have .xml file in the target, there is no problem with the target. It feels like that. Where is this configured?
is there a problem?
