I have created custom Java Authenticator and trying to import Zip file but it is giving me below error.
I believe you are trying to import it as an extension instead of doing an import as a file ?
Yes we were trying using Extension not file import. We have resolved our issue by compiling it using Ant. Gradle Compilation is not working . Mean if create Zip using Ant it is working but with Gradle it is not.
That's great if you were able to resolve it .But it must work with Gradle as well .I build every extension which Gradle only .
Still this is an issue for you ? if this is resolved please mark the right answer as solution .If not ,explain this more or open a new Thread .
