STM32F302K8 Reset Pin Not Connected

I have STM32F302K8U6TR MCU. Normally, I can program this MCU by St-Link successfully, I decided to try to program the MCU by J-Link in SWD mode. However, whenever I try to program by JLink Command Line (JlinkCommand.jlink), I get this error "can not attach to CPU. Trying connect under reset" in command line interface. I have connected and checked cable connection many times. When I look up in schematic, I have noticed that, reset pin not connected to programmer. It is always active high. Is it always required to connect reset pin to J-Link programmer. Is there a way to program without reset pin because I can program easily by St-Link without connecting reset pin to programmer. Any help will be appreciated.
