I've been using processing 1.5.1 with eclipse for a while without problem, and now I'd like to transfer one of my projects built under 2.0a4 in eclipse.

The test project I made is below :

1. import processing.core.*;
2. 
   
3. public class ProcessingTest extends PApplet {
5. public static void main(String args[]) {
6. PApplet.main(new String[] { "ProcessingTest" });
7. }
9. private static final long serialVersionUID = 1L;
10. int i = 0 ;
11. public void setup() {
12. size(640, 320, P3D);
13. }
15. public void draw() {
16. background(i++);
17. if (i == 255) i = 0;
18. }
19. }
