Meaning

A runtime classpath conflict: two versions of the same library, or a dependency upgraded without recompiling. The message names the missing method signature.

Common causes

  • Dependency version conflict (transitive)
  • Compile vs runtime classpath differ
  • Mixed Spring Boot / library versions

⚡ Quick fix

  1. Run mvn dependency:tree / gradle dependencies to find duplicates
  2. Align versions with a BOM
  3. Clean rebuild

Detailed fix by platform

Java

  1. mvn dependency:tree -Dincludes=com.fasterxml.jackson.core

How to diagnose

  1. Method — Which class/method signature?
  2. Versions — Which JAR provides it at runtime?
