I still don't understand how this happened. Was the dependency hosted in other place?
Dependencies CAN NOT be removed from central to avoid these issues. https://central.sonatype.org/articles/2014/Feb/06/can-i-change-a-component-on-central/ The question is where was this dependency coming from? and how can our build be so brittle to be broken on a 'optional' dependency, error-prone. How can we prevent this from happening in the future? On Wed, Jul 8, 2020 at 8:59 PM Pablo Estrada <pabl...@google.com> wrote: > > Ah that's annoying that a dependency would be removed from maven.
