Hi,
Did you find any way for ServiceResourceTransformer to work for
multiple services for same interface ? I am facing same issue in year 2019
with latest versions of maven shade plugin and of Dropwizard. I am able to
do same workaround as of yours. But not able to find what shade plugin can
offer for this problem.
