I completely agree. I know that there has been some work on command line ergonomics for this stuff, but my hope is that after the bulk of the Leyden work is done, another project starts up, aimed at unifying all of the various disparate tools that modern Java now has. You have training runs to generate bytecode/compiled code, you have jlink to create a distributable JRE for your app, leaning on jdeps and various other tools to correctly create it, you have to venerable jar file, but all in all the process of actually getting a java project ready to distribute in a way that doesn't presuppose a relevant pre-installed JRE on the user's side, and which takes advantage of the various facilities available to modern Java is still a pretty bespoke and painful process.

Compared to Go and Rust, and just throwing a static binary to someone or some server, Java kind of sucks. And that's unfortunate because the language, the runtime, and even the dependency situation all feels pretty competent, there's not some huge gulf that makes Java "old". Its really just the every about setting up a project and then distributing it, so the "start" and "end" of a project, that currently sucks, and I fear that so much of the great work the Java team is doing is going to go largely unused if they don't work to make it easier for the average developer to utilize it.
