[TEST] Missing Test Summary

I followed the "build from source" instructions, and besides the (usual) java installation problems, all fine.

running the tests with ./gradlew test -x aion_api:test resulted in this final output:

BUILD SUCCESSFUL in 13m 35s
92 actionable tasks: 33 executed, 59 up-to-date

which tells me of course not much about the tests (and makes me wonder if the test actually ran, 'cause naturally I went to the kitchen after starting the test-run...)

Expected Behavior

A summary of the tests is shown.

Further Info

(not sure here why the gradle developers do not include such essential functionality out-of-the-box)

A quick lookup shows that this is a standard-problems, with some existent solutions:
