Upgrade to SDK 7.30

I am using Eclipse IDE for Java Developers Version: 2020-03 (4.15.0)

My projects were running fine on Connect IQ 6.4.2, I tried to upgrade to 7.3.0 so I could support the Fenix 8 watches. This produced a hole list of errors

BUILD: ERROR: Unable to parse command line arguments: Unrecognized option: -s
BUILD: usage: monkeyc [-a <arg>] [-b <arg>] [--build-stats <arg>] [-c <arg>] [-d <arg>]

BUILD: [-u <arg>] [-v] [-w] [-x <arg>] [-y <arg>] [-z <arg>]

I have project.typecheck = 0 in the Monkey.jungle file.

When I revert back to 6.4.2 I can only get the older watches to run on the simulator.
