Why I am getting this exception with Google CAlendar library using java?

I just tried to compile a small prog for testing purposes in java. I added the Google Calendar library and to test whether it works I tried the following codes.

package googlemaptest;

import com.google.gdata.client.calendar.CalendarService;
import com.google.gdata.client.calendar.CalendarService.Versions;

/**
 *
 * @author vimal
 */
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        System.out.println("VErsion testing ..........."+CalendarService.CALENDAR_SERVICE );
        System.out.println("VErsion testing ..........."+CalendarService.DEFAULT_VERSION  );// this is line 24 in my codes
    }

}

I expected it to return me the calendar version and its name but in return it returned me something like this:

VErsion testing ...........cl
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code
        at googlemaptest.Main.main(Main.java:24)
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

I profiled the file and it came up wd the following exceptions

Since I am using this library for the first time, I do not have much knowledge about the exception. Can anyone tell me why this is happening and how I can sort this out?

The error message means that there was a compiler error. But the code looks fine. Perhaps it is outdated? In Eclipse: Try Project | Clean.

Eclipse will tell you about compile errors in the "Problems View" (Not the "Error View which is for bugs in Eclipse itself). You can open it with Window | Show View | Problems.

My guess is that you're trying to run the code in Eclipse, which does let you run code which hasn't actually compiled successfully.

Look at the compiler errors. They will help you out.
