Kwalitee Issues


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

Error: '' for 'Pod::Simple' is not a valid version. (requires -> Pod::Simple) [Validation: 1.2];'' for 'Test::Exception' is not a valid version. (build_requires -> Test::Exception) [Validation: 1.2]


List all used modules in META.yml requires


  • Email::Address


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

Error: 0.92,0.93


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: Mail::SimpleList, Mail::SimpleList::Alias, Mail::SimpleList::Aliases


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


  • Config
  • Cwd
  • File::Copy
  • File::Path
  • File::Spec
  • lib
  • strict
  • warnings


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


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