Externilise Changelog from jar file

Hey, We have integrated liquibase with spring boot application,we also developed gui to apply those queries on database insted manually with mvn command.
Currently we kept our changelog files under src/main/resources/db/changelog.
But with this scenario for every new changeset, we have to build the jar and deploy.
So we want to keep the changelog files outside jar file.
Like below dir structure we are trying to keep but it is unable to pick that changelogs from outside jar file.

myjarfile.jar
mychangelogs/master-changelog.yaml
