Acabei de começar o curso, estou usando o eclipse e tenho o seguinte erro Description Resource Path Location Type Archive for required library: 'C:/Users/JoãoMarcos/.m2/repository/org/springframework/boot/spring-boot-autoconfigure/1.5.6.RELEASE/spring-boot-autoconfigure-1.5.6.RELEASE.jar' in project 'rest' cannot be read or is not a valid ZIP file rest Build path Build Path Problem

apenas alterei o pom.xml, conforme está escrito acima.

Já verifiquei e o arquivo spring-boot-autoconfigure-1.5.6.RELEASE.jar está na pasta correta

Como corrigir esse problema?
