Android ant compile fails: java.lang.NoClassDefFoundError: com.android.jarutils.SignedJarBuilder

So I created my build.xml from scratch using the android utility:

$ /opt/android-sdk-linux_86/tools/android create project --target android-6 --name Dash --path . --activity Main --package com.gtosoft.dash

Then I try to kick off a compile, but it fails!

$ ant release

I'm at a loss for why it's complaining about com.android.jarutils.SignedJarBuilder

EDIT: After re-installing the SDK I have the same problem :(

$ ant -v release:

It sounds like (possibly) a corrupt SDK. Have you tried downloading it again?

Another alternative is to run ant -v instead of ant. That will produce a great deal of diagnostic output and may well help you to figure out what's going on .
