 Enforcer plugin not able to detect this duplicate dependency coming via transitive dependency and project gets build successfully. Is there any way to define any rule to enable the same?

org.apache.maven.plugins maven-enforcer-plugin 3.0.0 no-duplicate-declared-dependencies enforce

```

Research direction

Start by reproducing the reported dependency graph with the Maven Enforcer Plugin 3.0.0 and the shown banDuplicatePomDependencyVersions rule in a pom file. Check whether the duplicate dependency arrives through a transitive dependency and whether the build fails; done means the expected behavior is reproduced and the rule's handling of that case is verified.
