thanks

My guess would be that you either have outdated configuration or outdated changelogs.

hi,
i made a git clone of the project. so I have to be up to date. we took version 4.12. it is easier to compile. getting started with version 4.13 seems complicated
thanks

Version 4.12 uses Liquibase verson 3.x.x, so that's definitely not what you have.

I think you need to take a bit of time to understand the code and tools you are using before asking for any more help.
