Hi,

 

While executing a program to generate AST from a program source code,

I got following error on console:

 

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/runtime/CoreException
 at java.lang.ClassLoader.defineClass1(Native Method)
 at java.lang.ClassLoader.defineClass (Unknown Source)

 at java.lang.ClassLoader.loadClass(Unknown Source)
 at java.lang.ClassLoader.loadClassInternal(Unknown Source)
 at A1.main(A1.java:14)

 

The program code is :

 

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

import org.eclipse.jdt.core.dom.ASTParser;

public class MyAST

{

     public static void main(String[] args) throws FileNotFoundException,IOException

    {
  
            ASTParser ap=ASTParser.newParser(1);
            FileReader fr=new FileReader("");
            char[] s=new char[400];
            int i=fr.read(s);
            ap.setSource(s);
  
    }

}
