Estou com problema no início do projeto do livro java EE

Estou com erros na ide red hat codeReady studio, abaixo está o print com os erros, alguém pode me ajudar?
Estou usando a versão server da JRE e JDK = jdk1.8.0_301

Abaixo segue meu arquivo de pom.xml, comentei a linha conforme a página 12 do livro me recomendou.
