Kwalitee Issues


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


Add a section called "LICENSE" to the documentation, or add a file named LICENSE to the distribution.


Add =head1 LICENSE and the text of the license to the main module in your code.


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

Error: Expected a map structure from string or file. (requires) [Validation: 1.0]


Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.

Error: ExtUtils::Liblist, FindLib, Term::Gnuplot


Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 0.90380905,1.26


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


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


Add tests or move to the t/ directory!


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.


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.


Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.


  • ExtUtils::Liblist
  • ExtUtils::Liblist::Kid


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: ExtUtils::Liblist, FindLib, Term::Gnuplot


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).
