Kwalitee Issues


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


Add a MANIFEST to the distribution. Your buildtool should be able to autogenerate it (eg "make manifest" or "./Build manifest")


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

Error: Cannot find MANIFEST in dist.


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.


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.


  • Net::SMTP


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: Net::SMTP::Retryable


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).
