Android Studio Gradle: Please remove usages of `jcenter()` Maven repository from your build scripts / JCenter is at end of life
Move mavenCentral() above jcenter().
do a clean/build on your project.
comment out jcenter()
By moving mavenCentral() above jcenter(), mavenCentral() now becomes the primary repository for all non Google artifacts. By doing a clean and build, all artifacts are now moved to mavenCentral().
I had to look this up and tried it. I went from all heck breaking loose after I removed jcenter() to being able to build my final project for school again.
For koin, change the group id from org.koin to io.insert-koin - the latter is published on maven central.
For chartboost, you can use the following repo:
maven { url "https://dl.bintray.com/google/mobile-ads-adapters-android/"}Also note that there are newer versions such as koin 2.2.2 / 3.0.1 and chartboost 8.2.0.0. Older versions are likely not republished in non-jcenter repos.
mvnrepository is a good service for locating packages.
just commenting out jcenter() will help,mavencentral() is already above jcenter.
