jcenter is no longer active and in read-only mode. While this wouldn't be a problem
it also times out a lot here and on GHA:

> Could not resolve io.github.aakira:napier:1.5.0.
    > Could not get resource 'https://jcenter.bintray.com/io/github/aakira/napier/1.5.0/napier-1.5.0.pom'.
    > Could not GET 'https://jcenter.bintray.com/io/github/aakira/napier/1.5.0/napier-1.5.0.pom'.
        > Read timed out

So get rid of it and use mavenCentral instead.
