language translation

hi,I have included a jar file- google-translate-api-java 0.97.jar and this is my code...

import com.google.api.translate.Language;

import com.google.api.translate.Translate;

public class Main {

public static void main(String[] args) throws Exception {

Translate.setHttpReferrer("http://ift.tt/QqZk6x");

String translatedText = Translate.execute("Bonjour monde le",Language.FRENCH, Language.ENGLISH);

System.out.println(translatedText);

}

}

and I got the following error

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code

how to clear it???? thanks in advance
