“Debug certificate expired” error in eclipse android plugins

I am using eclipse android plugins to build a project, But i am getting this error in the console window: [2010-02-03 10:31:14 - androidVNC]Error generating final archive: Debug certificate expired on 1/30/10 2:35 PM! Does anyone know how to fix it?

Fix  Delete your debug certificate under ~/.android/debug.keystore (on Linux and Mac OS X); the directory is something like %USERHOME%/.androidon Windows. The Eclipse plugin should then generate a new certificate when you next try to build a debug package. You may need to clean and then build to generate the certificate.
