Build fails because of empty osgi.enroute.examples.proxycache.provider:test

[GiovanniLR]

Hello,
I've downloaded the examples zip file.
Running 'gradle build' on the root directory of the examples, fails with the message:
"
:osgi.enroute.examples.proxycache.provider:test

osgi.enroute.examples.proxycache.provider.ProxycacheImplTest > junit.framework.TestSuite$1.warning FAILED
junit.framework.AssertionFailedError at TestSuite.java:97
"
As given test is empty, the build can succeed by editing the test file and commenting/removing it.

For the record, I am using gradle 2.4 on OS X 10.12.2.
Kind regards
