Quando eu realizo o mvn verify, a BUILD fica como SUCCESS. Porém, quando vou verificar o report no .html, fica com 0%. Depois testei fazer mvn jacoco:check, curiosamente a BUILD mostra esse erro:

Acredito que esteja faltando um parâmetro de @Rules no meu código, mas é estranho que o professor não precisou se preocupar com isso na aula. Segue a seguir meu pom.xml (com muitas modificações, pois estou usando o Windows pra estudar isso...)

Descobri o problema. Eu fiz questão de rever o vídeo do professor, e entendi que era importante sempre pegar a ÚLTIMA versão do jacoco-maven-plugin.

Então , para quem estiver com problema similar ao meu.. primeiro deletem o pmd e jacoco no terminal:

mvn clean verify
mvn clean jacoco:prepare-agent
mvn clean jacoco:report

Depois, coloquem o maven-pmd-plugin mais atual no pom.xml Feito isso, no terminal digite: 1º mvn pmd:pmd 2º mvn verify

Depois, coloquem o jacoco-maven-plugin (ÚLTIMA versão) no pom.xml. (com o goal -> prepare-agent (primeiro)) Feito isso, no terminal digite: 3º mvn jacoco:help 4º mvn verify

Depois, (com o goal -> report (segundo)) Feito isso, no terminal digite: 5º mvn verify
