Linkage Checker to report which version of a library has expected symbols.

Regarding the error below, it would be nice if it can show which versions of Guava (1) curator-client 4.2.0 uses and (2) the class path actually contains.

Class com.google.common.reflect.TypeToken is not found;
  referenced by 6 class files
    org.apache.curator.shaded.com.google.common.eventbus.SubscriberRegistry (curator-client-4.2.0.jar)
    org.apache.curator.shaded.com.google.common.reflect.Element (curator-client-4.2.0.jar)
    org.apache.curator.shaded.com.google.common.reflect.ImmutableTypeToInstanceMap (curator-client-4.2.0.jar)
    org.apache.curator.shaded.com.google.common.reflect.Invokable (curator-client-4.2.0.jar)
    org.apache.curator.shaded.com.google.common.reflect.MutableTypeToInstanceMap (curator-client-4.2.0.jar)
    org.apache.curator.shaded.com.google.common.reflect.TypeToken (curator-client-4.2.0.jar)

After getting the error, we can report the different Guava versions by resolving the dependency of the Maven artifact of the source class.

Does Maven Central Index help?

The index turned out not to contain methods and fields.

I call the capability "hint" for now. A hint holds a map from a symbol to Maven artifact.
