Maven deploy and 422 Unprocessable Entity error

Hi guys,
I am trying to maven deploy my jar files using maven deploy command,
when I try to maven deploy it says:

FireflyLuciferin: Failed to deploy artifacts: Could not transfer artifact org.dpsoftware:FireflyLuciferin:jar:1.5.2 from/to github ( Transfer failed for 422 Unprocessable Entity -> [Help 1]

maven package works well and the artifact works well.

any idea on how to solve?

fixed it using an lowercase artifactid.
artifactid must be lowercase!
