Unable to build extensions

Hi, today, after syncing with the latest commits, extensions are not being generated.

I get an empty folder upon building.

Hi Pavitra,

This is a known issue as we are in the process of upgrading the extensions system. You will have to temporarily roll back to commit 409fc9cc in order to build extensions that will work with App Inventor production and its derivatives. We will be sending an announcement out soon with details about the upgraded extensions mechanism once we are finished. Expect more updates over the next few days.

Regards,

Evan

This should be fixed on the latest master.
