Spring Deprecate JOptCommandLinePropertySource

Affects: 6.x

Unfortunately JOpt Simple seems to be dead:

• Last Release: Jul 13, 2017
• Last Alpha: Sep 11, 2018
• Last Commit: Aug 4, 2021

(IMHO) All this does make it a bad option as a reference implementation for an advanced CommandLinePropertySource. It would be better to replace it with something actively maintained library. Some candidates might be:

• JCommander
• picocli
• Maybe Commons CLI - but they didn't release and new version since 2021...
• Airline 2 might also be an option, but seem less common

Thanks for the report.

We've decided to deprecate our support for JOptCommandLinePropertySource and do not consider a replacement at this time.

Reopening to revert the deprecation of CommandLinePropertySource and SimpleCommandLinePropertySource, since we have discovered that Spring Boot actively uses SimpleCommandLinePropertySource in org.springframework.boot.SpringApplication.
