Publishing uberjars to AWS S3 buckets

Maven command or Clojure lib someone made that uploads a jar file to a S3 bucket?

aws s3 cp uberjar md5sums

https://github.com/kennyjwilli/s3-mvn-upload - uploads a jar file to Aws S3

Without md5sums or similar checksum file, you wiil receive this message from tools-deps
"Download corrupted: Checksum validation failed, no checksums available."

The jar will works (i.e., jvm starts up with the jar on the cp) but better to add the checksum files

the correct way is to compute an md5 or sha1 checksum for the jar and upload those (and ideally to gpg sign all of those files as well).

I do not know of a tool that does that (although I have started working on one)

an example of what goes into maven central is something like this: https://repo1.maven.org/maven2/org/clojure/tools.deps.alpha/0.8.677/
how that all gets created and uploaded is quite complicated, and clojars does much less (and even less is really required)

really, just the jar and the md5 or sha1 file (and ideally the pom) are probably sufficient

you can use a tool like sha1sum or md5sum to make that

there is also a version metadata file that should be updated too (like https://repo1.maven.org/maven2/org/clojure/tools.deps.alpha/maven-metadata.xml) if you want something like RELEASE version to work.

I would like to handle a) clojars b) s3 and c) maven central in that order which I think handles both the most common and easiest items first
there are multiple options on each and it is way harder than it should be for sure

Start by reviewing the referenced s3-mvn-upload project and the tools-deps checksum failure, then compare the artifact files and metadata shown in the Maven Central example. Done would require a defined approach for publishing to Clojars, S3, and Maven Central, including checksums and the requested metadata.
