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.

Recommended CLI parsing libraries
Scallop is great -- it allows you to wrap entire functions and routines inside calls which pass arguments (like --name) and use them.

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

"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.

"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).
