use of com.robo4j.core.RoboBuilderException in project robo4j by Robo4J.

the class AccelerometerExample method main.

public static void main(String[] args) throws RoboBuilderException, IOException {
    RoboBuilder builder = new RoboBuilder();
    InputStream settings = RoboClassLoader.getInstance().getResource("accelerometerexample.xml");
    if (settings == null) {

    builder.add(settings);
    builder.add(AccelerometerProcessor.class, ID_PROCESSOR);
    RoboContext ctx = builder.build();
    System.out.println("State before start:");
    System.out.println(SystemUtil.printStateReport(ctx));
    ctx.start();
