Kwalitee Issues


Remove all letters from the version number. If you want to mark a release as a developer release, use the scheme 'Module-1.00_01'


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.


  • MANIFEST (16) does not match dist (20):
  • Missing in MANIFEST: lib/LEGO/NXT/, lib/LEGO/NXT/, lib/LEGO/NXT/, lib/LEGO/NXT/, t/01_basic.t
  • Missing in Dist: t/00_basic.t


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 'gnu' is invalid (license) [Validation: 1.0]


Fix the version(s).


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: LEGO::NXT::Simple


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.


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: LEGO::NXT::BlueComm, LEGO::NXT::MacBlueComm, LEGO::NXT::Simple, LEGO::NXT::USBComm


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).
