Can't run/compile source in Eclipse

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Opening and selecting the checked-out source into Eclipse and selecting Run 
> Run. 

What is the expected output? What do you see instead?
I expect the application to compile and run on the Android emulator or on a 
device.

What version of the product are you using? On what operating system?
Replica Island source v1.4, Eclipse Helios Service Release 2, and OS X 10.6.8

Please provide any additional information below.
Eclipse tells me to fix the errors in the application when attempting to run. 
The error is in Game.java, line 84, and the red line is under VERSION_CODES.

final int sdkVersion = Integer.parseInt(Build.VERSION.SDK);
            if (sdkVersion < Build.VERSION_CODES.ECLAIR) {
                mTouchFilter = new SingleTouchFilter();
            } else {
                mTouchFilter = new MultiTouchFilter();
            }

It seems that the R.java file is missing. It should be under the gen/ folder. 
Currently I have the same problem. As long as I know, it should be 
auto-generated at build time with the ANT tool but it doesn't.

It worked for me (svn rev 7). I added the project under Eclipse, and when I got 
the errors related to R.java, I simply cleaned and rebuilt it.
