Can Guice be configured to hide the class path in stack traces?

问题

Guice's stack traces can get so verbose that they are very painful to read. Here's an example:

1) No implementation for java.util.Set<com.mydomain.myapp.android.activities.catbrowser.generalizedbrowser.listview.helpers.databaseitem.itemmanipulators.ItemManipulator<com.mydomain.myapp.flash.Cat>> annotated with @com.google.inject.assistedinject.Assisted(value=) was bound.
  while locating java.util.Set<com.mydomain.myapp.android.activities.catbrowser.generalizedbrowser.listview.helpers.databaseitem.itemmanipulators.ItemManipulator<com.mydomain.myapp.flash.Cat>> annotated with @com.google.inject.assistedinject.Assisted(value=)

...

If I could hide the classpath, it would look like:

1) No implementation for Set<ItemManipulator<Cat>> annotated with @Assisted(value=) was bound.
  while locating Set<ItemManipulator<Cat>> annotated with @Assisted(value=)

Is there any way to configure Guice to do this?

So the answer is no.

If you take look at guice source code you will find com.google.inject.internal.Errors class that is responsible for building error messages. In this class it is coded that the Key is converting the following way:

  new Converter<Key>(Key.class) {
    public String toString(Key key) {
      if (key.getAnnotationType() != null) {
        return key.getTypeLiteral() + " annotated with "
            + (key.getAnnotation() != null ? key.getAnnotation() : key.getAnnotationType());
      } else {
        return key.getTypeLiteral().toString();
      }
    }
  }

Next step is to take a look at TypeLiteral#toString method:

  @Override public final String toString() {
    return MoreTypes.typeToString(type);
  }

Where MoreTypes#typeToString is a static method that cannot be configured

  public static String typeToString(Type type) {
    return type instanceof Class ? ((Class) type).getName() : type.toString();
  }
