The following link from the README does not work:

https://oss.sonatype.org/content/repositories/snapshots/com/puppycrawl/tools/checkstyle/

It returns 404 Not Found:

$ curl -o - -I https://oss.sonatype.org/content/repositories/snapshots/com/puppycrawl/tools/checkstyle/

HTTP/2 404

The new Maven Central link for checkstyle is https://central.sonatype.com/artifact/com.puppycrawl.tools/checkstyle. However, I do not see any SNAPSHOTs being uploaded.
