If you're using Gradle + jcenter repository, it will fail.

I ran into this when building a Flutter mobile app, relying on Gradle to fetch dependencies.

There is more information here: https://blog.gradle.org/jcenter-shutdown

I was able to find all the dependencies I needed on the Maven Central repository, so it was a quick fix in my case.

Same, I've been banging my head against this issue for half of today and no resolve yet (ironically ran into this after I fixed a slew of unrelated iOS build issues). My issue is with sub dependency reliance on jcenter (e.g react-native-pdf). Given Java/Gradle isn't my domain of expertise, I can't yet find a clean way of intercepting bintray requests and subbing them out for Maven/Google hosted equivalents (which seem to exist).

I don't hold out much hope that JFrog will expedite a fix for this given their intention to phase out of service.
