Library Mismatch Issue in Spring Boot

Question

My Spring-boot Application worked perfectly until I began fiddling with spring boot and cucumber testing. Can't say exactly what went wrong but from my research it seems to be a library dependency mismatch in my pom.xml

Seems to me more of a missing dependency rather than a mismatched versions. — Yazan Jaber

you can safely remove this dependency:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <scope>test</scope>
</dependency>

via spring-boot-starter-data-jpa you already have a transitive dependency to spring-tx.

By explicitly binding spring-tx to the test-scope, you remove it from the compile-scope (mavens default scope)
