val jar = ToolProvider.findFirst("jar").orElseThrow()
        jar.run(null, null, "--create", "file=strat-game.jar", "--main-class=view.StratGame", "-C", outputDirectoryName, ".")

and the JRE has the java.util.spi.ToolProvider interface. In this interface it has int run(PrintWriter out, PrintWriter err, String... args); and

default int run(PrintStream out, PrintStream err, String... args) {
   // some implementation code
    }
