Когда я запускаю код ниже, я получаю следующую ошибку.
C:\Documents and Settings\BOS\Desktop\test>java -jar test.jar
Exception in thread "main" java.lang.NullPointerException
at sun.launcher.LauncherHelper.getMainClassFromJar(Unknown Source)
at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source)
У меня есть эти файлы в \ test directory = crimson.jar robosuite-api.jar и test.jar.
Вот пример, который они дают для запуска робота?
import com.kapowtech.robosuite.api.java.rql.*;
public class SimpleRunRobot {
public static void main(String[] args) {
if (args.length < 1) {
System.out.println("Usage: RunRobot <robotURL>");
System.exit(1);
}
try {
// Run the robot
RQLResult result =
RobotExecutor.getRobotExecutor().execute(args[0]);
// Output the results
System.out.println(result);
}
catch (RQLException e) {
System.out.println("An error occurred: " + e);
}
}
}
Почему это дает мне ту неизвестную ошибку источника?
