.Jar não envia o email

Pessoal, estou com um problema onde a classe de serviço EmailSenderService não está sendo encontrada. Detalhe que quando eu executo pelo eclipse, funciona e envia o email. Mas pelo jar, infelizmente não está encaminhando. Segue o erro:

Caused by: java.lang.ClassNotFoundException: br.com.camaroti.alex.emailSender.emailSender.service.EmailSenderService

O meu pom está ok, mas estou usando a versão 2.0.4 por estar utilizando uma versão mais atualizada do java.
