Jcenter will shut down soon

[Atemu]

I wanted to build NewPipe today but there's a jcenter outage and I'm unable to fetch the dependencies.

When googling for potential mirrors, I found this: https://blog.gradle.org/jcenter-shutdown

O_o

I wasn't even able to fetch the kotlin plugin with a clean GRADLE_USER_HOME. It's in mavenCentral too thankfully but even with that I get stuck at trove4j which isn't in mavenCentral nor Google's repo.

Apparently jcenter will go readonly at the end of the month, so this patch will need to be made to work rather soon if we want security patches from that point on:

Thank you for letting us know!
I have created PR to remove JCenter when possible: #5843
I could not resolve these dependencies:

com.google.android.exoplayer:exoplayer:2.11.8
com.google.android.exoplayer:extension-mediasession:2.11.8
com.nononsenseapps:filepicker:4.2.1
com.xwray:groupie:2.8.1
com.xwray:groupie-viewbinding:2.8.1
org.jetbrains.trove4j

Most of these already work on publishing their binaries on other platforms:

• Publish old releases to GMaven/google() (in addition to jcenter) google/ExoPlayer#5246 (comment)
• Migrate off Bintray lisawray/groupie#384
• https://github.com/spacecowboy/NoNonsense-FilePicker NoNonsesnse FilePicker is working on migrating their dependencies to Maven Central. For this reason, I guess we can expect to see their binaries published there, soon.

@Atemu Were you able to resolve any of those dependencies?

[Atemu]

My attempts didn't go much further than trying to get stuff from mavenCentral() instead either.

For some dependencies like trove, jcenter going readonly might not be that bad as it hasn't seen an update in years anyways.
Your approach of explicitly whitelisting these is the best we could do right now I think.

@TobiGr Looks like Exoplayer and trove4j have both moved to GMaven/mavenCentral. You may want to update #5843 to reflect that?
