Kwalitee Issues


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


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 'Class::Roles' is not a valid version. (requires -> Class::Roles) [Validation: 1.0];'' for 'IO::String' is not a valid version. (build_requires -> IO::String) [Validation: 1.0];'' for 'IPC::Open3' is not a valid version. (requires -> IPC::Open3) [Validation: 1.0];'' for 'Module::Build' is not a valid version. (requires -> Module::Build) [Validation: 1.0];'' for 'Test::Exception' is not a valid version. (build_requires -> Test::Exception) [Validation: 1.0]


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.


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).
