NoSuchFieldError: CONTEXT_SPAN_KEY with google-cloud-speech

[mertakdut]

Google cloud speech throws an error when version of endpoints-management-control-appengine-all is declared as either 1.0.10 or 1.0.11.

Here's the stackoverflow question about it: https://stackoverflow.com/questions/55643735/google-cloud-speech-nosuchfielderror-context-span-key

And I can't check the dependencies of endpoints-management-control-appengine-all. Nor maven. Resulting in having duplicate sources. Is this the purpose of -all libraries?
