I got this error after updating library com.google.firebase:firebase-core:16.0.6 to version 16.0.7.
Could not get resource \'https://dl.google.
try to provide it with the dependency it demands; the repository is mavenCentral(), not google():
// https://mvnrepository.com/artifact/com.google.firebase/firebase-measurement-connector-impl
implementation "com.google.firebase:firebase-measurement-connector-impl:17.0.5"
when looking closely, it's only the javadoc package which has no content, which has no effect on the jar/aar package, except that the documentation is missing.
