Not building after last update

[OnMusicApps]

Hello,

I was being able to use correctly the plugin until one hour ago, but now Phonegap Build is throwing an error. I believe it's related to the last update.
The error I'm getting is:

BUILD FAILED

Any idea if there is anything I can to to fix it?

Thanks.

What do you have set as minSdkVersion and targetSdkVersion?
