Kwalitee Issues


Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.


Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.


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.


  • MANIFEST (20) does not match dist (19):
  • Missing in Dist: META.yml


Sign the dist as the last step before creating the archive. Take care not to modify/regenerate dist meta files or the manifest.

Error: WARNING: This key is not certified with a trusted signature! Primary key fingerprint: 8231 2E41 472B 5F8D 86E3 6E30 FC06 4088 66B2 5843 No such file: META.yml ==> MISMATCHED content between MANIFEST and distribution files! <==


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


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.


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
