Hibernate 6 can't seem to resolve Custom Types specified in .hbm.xml files, throws MappingException

Hibernate Tools
1

We use .hbm.xml files along with hbm2java task to generate Entity classes from the .hbm.xml files we created.
For a certain use case we defined a Custom Type which we use in the mapping files.

Unlike hibernate 5, where it was able to resolve this custom type, in hibernate 6 it throws me an exception at compile time saying - org.hibernate.MappingException: Could not resolve named type : CustomTypeName.

Can anyone please suggest anything for this question, even we are facing this issue.

Hi,

Can you please create a reproducer for this bug that shows the problem? Just a minimal project setup (preferably Maven based).

Cheers,

I also recommend to try with the latest version: 6.6.10.Final

Currently we are using 6.6.5, let me try with 6.6.10.
