opentelemetry-javaagent-1.2.0.jar includes all dependencies and all exporters

[tobias-]

Describe the bug
opentelemetry-javaagent-1.2.0.jar includes all dependencies. While that is expected for opentelemetry-javaagent-1.2.0-all.jar, the one without -all should not include the exporters.

Steps to reproduce
Go to e.g. Maven Central and download the non-all version.

A)

unzip -v opentelemetry-javaagent-1.2.0.jar  | grep -F " inst/"

B)

unzip -v opentelemetry-javaagent-1.2.0.jar  | grep -F "inst/io/opentelemetry/exporter/"

What did you expect to see?
A) I believe this should return an empty response
B) I'm sure this should return an empty response.

What did you see instead?
A) approx 15'000 files in
B) 142 files

What version are you using?
v1.2.0

Environment
Not relevant.

The agent doesn’t use code from the app so both versions are supposed to have dependencies, while the -all is supposed to in 
addition include all exporters. If even the non -all had no dependencies included it wouldn’t work as a javaagent.
