how to compile the java file generated by cup

Question

I downloaded the demo from http://www2.cs.tum.edu/projects/cup/ I got parser.java by command:

java -jar bin/java-cup-11a.jar cup/parser.cup

but when I compile parser.java by:

javac -classpath lib/java-cup-11a-runtime.jar parser.java

the result is:

cspro@Think:~/Desktop/template$ javac -classpath lib/*.jar -d .  parser.java
parser.java:104: cannot find symbol
symbol  : class Parser
location: class Example.parser
      if (args.length==0) new Parser(new Scanner(System.in,sf),sf).parse();
                              ^
parser.java:104: java_cup.runtime.Scanner is abstract; cannot be instantiated
      if (args.length==0) new Parser(new Scanner(System.in,sf),sf).parse();
                                     ^
parser.java:105: cannot find symbol
symbol  : class Parser
location: class Example.parser
      else new Parser(new Scanner(new java.io.FileInputStream(args[0]),sf),sf).parse();
               ^
parser.java:105: java_cup.runtime.Scanner is abstract; cannot be instantiated
      else new Parser(new Scanner(new java.io.FileInputStream(args[0]),sf),sf).parse();
                      ^
