@kdhrubo Is this older URL with Cloudflare hosted somehow? Should it point to https://repo1.maven.org/maven2/io/9tiger/db2rest/1.4.0/db2rest-1.4.0.jar
And if Cloudflare hosted, do we have some download tracking?
On central.sonatype.com they do NOT have download statistics if you recall:

Hello Thad,

At the moment this can not be done in Central Portal. We are working on that feature but we have no ETA.

Regards,
The Central Team

Seeing download statistics is nice to have...but the reality is that projects will integrate and pull down the .jar file directly from Maven repo through their build tools, and not be relying on an HTTP GET from a non-Maven storage CDN like Cloudflare.

Thoughts? What do you want to do here for this URL in the Docs?

Some of the users rely on jar downloads to use DB2REST. So it will be good to push the final jar to cloudflare storage and update readme
