Kwalitee Issues


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 (11) does not match dist (13):
  • Missing in MANIFEST: .gitignore, .tag-nodzil, META.json, lib/Scalar/Util/
  • Missing in Dist: MYMETA.json, MYMETA.yml


Take a look at the META.json Spec at (for version 1.4) or (for version 2), and change your META.json accordingly.

Error: Missing mandatory field, 'generated_by' (generated_by) [Validation: 2]


Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.


If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.


Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Scalar::Util::LooksLikeNumber


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


Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
