obrigado pelo comentário.
ainda hoje vou postar uns códigos.
Mas adiantando, né parece ser um erro de assinatura ou algo do tipo.
Quando eu vou executar o arquivo.jar aparece uma exceção e acredito ser do itextpdf, já pesquisei sobre, fiz exclusões de arquivos no pom.xml mas não adiantou.

Este é meu pom.xml
