generator-jhipster: Liquibase changeset generation failing

Hi,

After recently getting hot reload to work with my application (I think it’s working anyawy) I’m now running into errors during liquibase changeset generation. If I generate a new entity using -

yo jhipster:entity foo

and then run a gradle compileJava

this is the error that gets thrown :

I see a bunch of other errors about failing to find a watched folder for the directory so I’m not sure exactly what those are about.

Since gradle is putting my build files in ./build and not ./target I updated my application-dev.yml to read :

# You can add as many as folders to watch
# You just need to add a dash + the directory to watch
hotReload:
    enabled: true
    package:
      project: com.company.uclpreferences
