Can a JAR be signed such that macOS will accept it?

I have an executable JAR which I wish my macOS users to execute from Finder without any command-clicks, or configuration of the system security.

When the JAR is opened it Finder it presents the message:

“blah.jar” is from an unidentified developer. Are you sure you want to open it?

The JAR is signed though evidently not to Apple's requirements. Can anyone point me at a means of signing the JAR to placate Finder?

I am aware of javapackager but ideally don't want to build a separate deliverable for one operating system.

Apple has a distinct way to register yourself respectively your deliverables, see Developer ID. But right on the first page, it says:

A Developer ID certificate lets Gatekeeper verify that you’re a trusted developer when a user opens your app, plug-in, or installer package downloaded from outside the Mac App Store.

Note: it talks about apps, plug-ins, or installers.

Given the fact that Apple and MacOs are really not known for enthusiastic support of Java, my gut feeling is that signing JAR files isn't something they care about.

In other words: I very much doubt that you can convince MacOs to accept and run JAR files.
