Answer 1

From the logs, it seems Spring is picking a different version for groupId org.springframework.data than the one provided with spring-data-jpa . If you could match the versions of spring-boot-starter-web and spring-data-jpa , it should work.

Quick fix being: Remove the version number for spring-data-jpa and it will by default take the latest version, which in your case is 2.1.10.RELEASE .
