I have imported Appybuilder and installed. Everything OK and I’ facing the same issues here. Maybe it’s not because of Peter has pointed:
I think even we don’t use those components, they could generate this kind of issues… Or am I wrong?
EDIT: The error showed in my case was this:
GRAVE: Build 1 Failed: 1 Error: Your build failed due to an error in the JarSigner stage, not because of an error in your program.
I had exported the keystore from Appybuilder online and imported into Appybuilder offline…
