spring-boot maven dependency-management Java

I'm stuck on something that should probably be simple. I've looked through the documentation and I'm still confused about I've been struggling with this for a few days now and could really use some help. I recently added a new dependency to my Spring Boot project that uses the latest version of the 'spring-boot-starter-data-jpa' (2.5.6) and the application now fails to start with the behavior `Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/data/jpa/repository/config/EnableJpaRepositories`. I verified that the dependency is present in the `pom.xml` as follows: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> <version>2.5.6</version> </dependency> ``` Before adding this dependency, everything was working fine, and I could run the application using the `mvn spring-boot:run` command. To troubleshoot, I tried cleaning the project using `mvn clean`, and I even checked the `.m2` repository to see if the new dependency was correctly downloaded. Running `mvn dependency:tree` shows that the dependency is indeed there and is not conflicting with any other dependencies. Additionally, I confirmed that my `Java` version is compatible with Spring Boot 2.5.6 (I'm using Java 11). However, the behavior continues. I also checked my IDE's configuration and ensured that it is using the correct JDK. Has anyone encountered a similar scenario, or can anyone provide guidance on how to resolve this `NoClassDefFoundError`? Any insights would be greatly appreciated! This is part of a larger application I'm building. Thanks in advance! Thanks, I really appreciate it! I'd really appreciate any guidance on this.
