Kwalitee Issues


Add a README to the distribution. It should contain a quick description of your module and how to install it.


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

Error: License 'Perl' is invalid (license) [Validation: 1.4]


List all used modules in META.yml requires


  • List::MoreUtils
  • Win32::API


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


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: App::VideoMixer, App::VideoMixer::Filter, App::VideoMixer::Filter::Buffer, App::VideoMixer::Interpolators, App::VideoMixer::Source::FFmpeg, Config::PCF, OpenGL::Font, OpenGL::SimpleNames, OpenGL::Tools


List all modules used in the test suite in META.yml build_requires


  • File::Find
  • File::Spec
  • Test::More
  • strict
  • warnings


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.


Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).
