Groovy classpath issue

I have run the following code in this page RsyntaxTextArea using Java and i run the program exactly the way that is been mentioned in this site.And i'm getting the output as intended. But i have tried to modify this java code to Groovy code, something like:

import groovy.swing.SwingBuilder
import javax.swing.*
import java.awt.*
swing =  new SwingBuilder()
frame = swing.frame(title : "test", defaultCloseOperation:JFrame.EXIT_ON_CLOSE, pack:true, show : true, size :[100,100])
{
        panel
        {
             RSyntaxTextArea textArea = new RSyntaxTextArea();
             textArea.setSyntaxEditingStyle(SyntaxConstants.SYNTAX_STYLE_JAVA);
        }
}

And when i try to run this script as follows:

groovyc -classpath rsyntaxtextarea.jar TextEditorDemo.groovy 

I get the errors stating that:

groovy: 9: unable to resolve class RSyntaxTextArea 
 @ line 9, column 19.
        RSyntaxTextArea textArea = new RSyntaxTextArea();
                     ^

/home/anto/Groovy/Rsyntax/ST.groovy: 9: unable to resolve class RSyntaxTextArea 
 @ line 9, column 30.
        RSyntaxTextArea textArea = new RSyntaxTextArea();
                                ^

/home/anto/Groovy/Rsyntax/ST.groovy: 10: unable to resolve class RSyntaxTextArea 
 @ line 10, column 7.
         textArea.setSyntaxEditingStyle(Syntax开发者_如何学编程Constants.SYNTAX_STYLE_JAVA);

I guess i have made wrong in running the program. How i do i run the program in this case by defining the classpath too.

It doesn't look like you're importing the package for RSyntaxTextArea. Have you tried adding the following imports to your program?

import org.fife.ui.rtextarea.*;
import org.fife.ui.rsyntaxtextarea.*;

This code should do what you want... You needed to add the RSyntaxTextArea into the view (using the widget method)

You also needed to add it into a JScrollPane, so that it scrolls nicely when full.

import groovy.swing.SwingBuilder
import java.awt.BorderLayout as BL
import static javax.swing.JFrame.EXIT_ON_CLOSE
import org.fife.ui.rsyntaxtextarea.*

RSyntaxTextArea textArea = new RSyntaxTextArea()
textArea.syntaxEditingStyle = SyntaxConstants.SYNTAX_STYLE_JAVA

swing =  new SwingBuilder()
frame = swing.frame(title:"test", defaultCloseOperation:EXIT_ON_CLOSE, size:[600,400], show:true ) {
  borderLayout()
  panel( constraints:BL.CENTER ) {
    borderLayout()
    scrollPane( constraints:BL.CENTER ) {
      widget textArea
    }
  }
}

edit

Without using widget, your code would need to look something like this:

import groovy.swing.SwingBuilder
import java.awt.BorderLayout as BL
import static javax.swing.JFrame.EXIT_ON_CLOSE
import org.fife.ui.rsyntaxtextarea.*

RSyntaxTextArea textArea = new RSyntaxTextArea()
textArea.syntaxEditingStyle = SyntaxConstants.SYNTAX_STYLE_JAVA

swing =  new SwingBuilder()
frame = swing.frame(title:"test", defaultCloseOperation:EXIT_ON_CLOSE, size:[600,400], show:true ) {
  borderLayout()
  panel( constraints:BL.CENTER ) {
    borderLayout()
    sp = scrollPane( constraints:BL.CENTER )
    sp.viewport.add textArea
  }
}
