Nick Dimiduk commented on PHOENIX-1977:
---------------------------------------
I now think this is the wrong approach. The {{client}} assembly is an uberjar
that packages everything needed to drop it into an external tool and use JDBC.
Thus, I think hacking up the classpath based on what's installed locally is the
wrong approach. Over in
[components-major-client.xm|https://github.com/apache/phoenix/blob/master/phoenix-assembly/src/build/components-major-client.xml#L33-L54]
it looks like we enumerate all dependencies. I think we can drop the act and
let maven resolve them for us. Maybe there was a reason for including them
explicitly (the comment implies the author considered an exclude list). Let me
try some things.
