I would like to run an app from my service using the java processBuilder class however that app has command line arguments that have values that have dashes in them.
e.g. >app -b 8 -e u-law
when I create a processBuilder instance and pass in "-e u-law" as one of the command arguments, it can't seem to handle the dash in the argument value. Is there a way around this to get it working?
You need to add each String token, that is, each command sub-String that is separated by white space, separately to the ProcessBuilder's command parameter array or List. For this command line,
e.g. >app -b 8 -e u-law
You have 5 String tokens, app, -b, 8, -e, and u-law (since you have no gap between the u and the dash). You could then do something like this:
List<String> list = new ArrayList<>();
list.add("app");
list.add("-b");
list.add("8");
list.add("-e");
list.add("u-law");
ProcessBuilder pBuilder = new ProcessBuilder(list);
alternatively you could use an array of 5 Strings for this,
String[] commands = {"app", "-b", "8", "-e", "u-law"};
ProcessBuilder pBuilder = new ProcessBuilder(commands);
