Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

GraalVM for JDK 21 is here
Picocli allows using a compiler annotation processor to generate classes at compile time instead [0].

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
Picocli is a pretty good one for writing CLI apps

“Why I develop on Windows”
"and there are simply no good command line input parsing libraries for Java."
Looks like author missed the most obvious and popular OSS one: https://picocli.info/

Java 20 / JDK 20: General Availability
The command line example gave me the "ick". It is usually preferrable to parse the command line arguments into one instance of a custom "command class", rather than into a list of things. Like jcommander, picocli or jbock do.
-
any opinion good or bed about a code that smells?
Complex argument parsing needs to be auto-generated by libraries like picocli. Even if you need something custom, it'd be quicker to write an Annotation processor from scratch than editing that file.

Owl: A toolkit for writing command-line user interfaces in Elixir

"Picocli-based applications can be ahead-of-time compiled to a GraalVM native image, with extremely fast startup time and lower memory requirements, which can be distributed as a single executable file."

Building a Java CLI. How can I make it more powershell-friendly
Using picocli to handle your command line options gives you the best chance to automatically generate an ArgumentCompleter script in the future, but won't help you today (other than possibly making your command line handling more standardized & easier).

com.lihaoyi Scala: Executable Pseudocode that's Easy, Boring, and Fast
In Kotlin, I've been having a great time with kotlinx-cli. No macros involved or magic involved, and it's closer to the author's own ideals.

Guides for Kotlin scripting use case
(And some less good ones https://github.com/Kotlin/kotlinx-cli, despite being official)

How can I make my class more reusable?
Not exactly sure what you're doing, but check out https://github.com/Kotlin/kotlinx-cli which is an official multiplatform solution for parsing incoming options. If you can use it in your case, great! If not, you might at least be inspired by the API (and how extensive even a "simple" idea can get).

New Project: CLI to transform Excel spreadsheets to JSON (in Kotlin)
For CLI programs in Kotlin, I suggest taking a look at kotlinx-cli or, especially, Clikt, for idiomatic Kotlin code without annotations and such. Of course, after having already written the program, you're most likely not gonna switch that out, but I just wanted to inform you about that.

Cli frameworks for Kotlin
What about the official command line parser from jetbrains? https://github.com/Kotlin/kotlinx-cli

Absolute beginner - readLine() convert input to Int
I think, you can use libs for that. ex: Clikt, kotlinx.cli, picocli

Started Learning Kotlin 3 days ago, this is my first little project
Nice work! Welcome to Kotlin, it’s quickly becoming my favourite language. (Former PHP, current Java dev here). You should check out https://github.com/Kotlin/kotlinx-cli if you want to take it to the next level.

Is Kotlin Native ready for CLI tools development ?
There is https://github.com/Kotlin/kotlinx-cli but you'll have to weigh this against quality and completeness of third party efforts as you've already discovered (in any case you'll probably need multiple libraries).
