vraptor や hibernate などの一部の jar をアップグレードするために pom.xml を更新するときに問題が発生します...更新Tomcatの起動時にこのエラーが発生しました：

Figured out what was happening with the upgrade process. I'm using the project, a jar that manages instances of EntityManager vraptor-jpa, when I kept the update, it occasioned the error. Compatibility could be:

vraptor in version 3.4.2, use the plugin vraptor-jpa-4.0.0.jar

Vraptor in version 3.5.3, the plugin uses vraptor-jpa-1.0.1.jar

This change was enough to solve the problem.
