JsonParseException when trying to run spring boot

Question

Using the following command: java -jar target/spring-boot-config-0.0.1-SNAPSHOT.jar --spring.application.json='{"server":{"ip":"192.168.145.78"}}' I get a org.springframework.boot.json.JsonParseException: Cannot parse JSON exception. I have no idea why, my command seems to be correct. Could anybody help me with this. My application is simple:

public class SpringBootConfigApplication {
    private static Logger log = LoggerFactory.getLogger(SpringBootConfigApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(SpringBootConfigApplication.class, args);
    }

    @Value("${server.ip}")
    String serverIp;

    @Bean
    public CommandLineRunner values() {
        return args -> {
            log.info(" > The Server IP is: " + serverIp);
        };
    }
}

The full stacktrace is:

Use double quotations in outer string and escape them when defining keys and values

java -jar target/spring-boot-config-0.0.1-SNAPSHOT.jar --spring.application.json="{\"server\":{\"ip\":\"192.168.145.78\"}}"

Should be the case with Windows. Wonder whether same is required with a unix type environment

It works, but I wonder know why Spring official website uses single quotations? 2.2. JSON Application Properties

@LHCHIN, the doc mentions that those commands are run on a UNIX-based shell. Double quotes are for Windows.
