Where on earth are you getting these pin designations. Don't confuse the pins on the STM32F103 implementing the ST-LINK/V2 with the pins on the F030 you need to connect to a header.

The STM32F030 is going to use SWD via PA13 SWDIO (JTMS), PA14 SWCLK (JTCK), and NRST

As best I can tell the part does NOT support JTAG

The wouldn't preclude the use of the 20-pin 0.1'' header, and you could use a JTAG pod supporting Cortex-M0 and SWD
