Error of code with JSON

[ghost]

Expected behavior and actual behavior:

1. To run the code from a json and compile it.

   Exception in thread "main" org.joor.ReflectException: Compilation error: /io/github/xavierdd1st/TimeViewer.java:1: error: class, interface, or enum expected
   nullpackage io.github.xavierdd1st.commands;import java.time.Clock;import java.time.ZoneId;public class TimeViewer extends Command {public void command() {Clock clock = Clock.system(ZoneId.systemDefault());CommandParser.setOutput( clock.toString() );}}

Thanks for reporting.

I'm looking at the relevant code in your class that calls Reflect.compile():

public class CommandParser {
    private HashMap<String, Command> compiledCode = new HashMap();
    private HashMap<String, Reflect> compiledClasses = new HashMap();
    private static String output;
    String code;

    public void parseCode(Command command) {
        if (!this.compiledCode.containsKey(command.getInstanceID())) {

            for (int i = 0; i < command.getCode().length; i++) {
                code = code + command.getCode()[i];
            }
            Supplier<String> supplier = Reflect.compile(
                    "io.github.xavierdd1st." + command.getName(),
                    code).create().get();
            this.compiledClasses.put(command.getInstanceID(), (Reflect) supplier);
            this.compiledCode.put(command.getInstanceID(), command);
        }
    }

Notice how you did not initialise your String code member to an empty string, thus when you concatenate some code to it, there's going to be "null" at the beginning of your code, as you can see in the first statement of the error message:

nullpackage io.github.xavierdd1st.commands;

Hope this helps

Thanks a lot I never experimented with things like that.
