Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Change the permissions of Build.PL/Makefile.PL to not-executable.
Add =head1 LICENSE and the text of the license to the main module in your code.
Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.
Error:
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Fix MANIFEST (or MANIFEST.SKIP) to exclude dot directories from a distribution. Use an appropriate tool and avoid archiving your working directory by hand. If you switch your version control system, remove old VCS directories after you migrate.
Error: .git
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
