How to Sign and Release to The Central Repository with GitHub Actions

GitHub allows automated builds using GitHub Actions. A commonly asked question is how to release artifacts (packaged Java jars) built by Maven and Gradle to The Central Repository. The GitHub Actions documentation provides only part of the answer.

So, first, configure your Maven project for staging artifacts to The Central Repository, by reading through Configuring Your Project for Deployment and following those steps. Please make sure that the maven-gpg-plugin is configured to prevent gpg from using PIN entry programs, as follows:

<configuration>
  <gpgArguments>
      <arg>--pinentry-mode</arg>
 loopback

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

Tip

Have a look at git-conventional-commits , a CLI util to ensure these conventions, determine version and generate changelogs

logica --> nos permite validar e construir argumentos
       --> descreve com precisao um algoritmo
       
proposicao --> sentenca q e verdadeira ou falsa, nao pode ser ambos

negacao --> sempre inverte o valor logico da proposicao (¬p ou ¯p)

and --> quando ambos sao verdade o resultado e verdadeiro tambem (p ∧ q)
or --> quando pelo menos uma proposicao e verdadeira, o resultado tambem sera (p ∨ q)
exclusive-or --> quando um e verdadeiro e o outro e falso, o resultado sera verdadeiro(p ⊕ q)

Redes

• sistema de comunicação --> tudo que possibilita a informação sair de uma fonte para um destino

componentes de um sistema de informação

• mídia de transporte --> meio fisico
• técnicas de codificação dos sinais --> maneiras de transformar a informação em sinais analógicos para serem transmitidos
• protocolos de comunicação --> regras de como as mensagens devem ser enviadas, recebidas e interpretadas
• equipamento de acesso à mídia --> equipamentos encarregados de seguir as etapas do protocolo usado (como um roteador, placa de rede, etc)
