I am trying to use 'ant' to build my android application. But it fails when it is building a debug version of my application. Here is the error:
BUILD FAILED
/Users/michael/Programs/android-sdk-mac_x86/tools/ant/main_rules.xml:506: The following error occurred while executing this line:
/Users/samuel/Programs/android-sdk-mac_x86/tools/ant/main_rules.xml:236: com.android.sdklib.build.ApkCreationException: Debug Certificate expired on 1/5/11 8:29 PM

Can you please tell me how can I get a valid debug certificate?
Thank you.
From Android - Signing Applications:
Expiry of the Debug Certificate
The self-signed certificate used to sign your application in debug mode (the default on Eclipse/ADT and Ant builds) will have an expiration date of 365 days from its creation date.
When the certificate expires, you will get a build error. On Ant builds, the error looks like this:
debug: [echo] Packaging bin/samples-debug.apk, and signing it with a debug key... [exec] Debug Certificate expired on 8/4/08 3:43 PM
In Eclipse/ADT, you will see a similar error in the Android console.
To fix this problem, simply delete the
debug.keystore
file. The default storage location for AVDs is in~/.android/
on OS X and Linux, inC:\Documents and Settings\<user>\.android\
on Windows XP, and inC:\Users\<user>\.android\
on Windows Vista and Windows 7.The next time you build, the build tools will regenerate a new keystore and debug key.
