I'm getting this error message when trying to run a .java file using Spring Boot. This is my first project, I checked the resolution from previous posts -- #15020, but that has not helped. Please advise

You have mismatched versions of your dependencies on the classpath. If you need some help figuring out what they are and why it's happening, please follow up on Stack Overflow or Gitter. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements.

@Praveenvermatech Please see my comment above. Gradle's dependencies or dependencyInsight tasks will help you to see your dependencies' versions.

This happened to me in a new project I copied from a running one. I've Open JDK 14 and Oracle JDK 1.8 installed on my machine.
Clean install was working fine but I think some classpath files still need to be modified ,
Did a mvn eclipse:eclipse and disappeared.
