将 vRaptor 升级到 3.5.3 Java.lang.NoClassDefFoundError：br/com/caelum/vraptor/validator/Validator

问题描述 投票：0回答：2

我在更新我的 pom.xml 来升级一些 jar 时遇到了麻烦，比如 vraptor 和 hibernate...我的环境是，Web 项目，maven，tomcat 7，vraptor，jpa，osx mavericks，在更新 jar 之前，所有工作都很好，之后更新我在启动 tomcat 时遇到此错误：

关于错误我在其他包中找到了这个接口：br.com.caelum.vraptor.Validator 这是我的 pom.xml:

我真的找不到任何原因，如果有人遇到这个问题并且可以解决，请帮助我解决这种情况。

弄清楚升级过程中发生了什么。我正在使用该项目，一个管理 EntityManager vraptor-jpa 实例的 jar，当我保持更新时，它引发了错误。兼容性可能是：

vraptor 3.4.2 版本，使用插件 vraptor-jpa-4.0.0.jar

Vraptor 3.5.3版本，插件使用vraptor-jpa-1.0.1.jar

这个改变足以解决问题。

首先，我们将与您的图书馆一起阅读有关超级英雄装备的时间。验证 VRaptor 和 Hibernate 的版本，以便与朋友和朋友一起度过。这是一场与超级英雄的决斗，我们没有任何计划！

集市，“limpeza mágica”盛宴！执行命令 Maven“clean”和“install”，以保证项目的组织和依赖。 É como fazer uma festa de limpeza, e todos estão convidados!

啊，一个 estrutura do projeto é como a planta de uma casa，certo？ Verifique se tudo está no lugar certo, como se estivese Organizando o seu quarto. Às vezes, pequenos detalhes na Organização dos arquivos podem causar causar, e queremos que tudo seja bem arrumado!

Tomcat 没有记录有关问题的秘密。 Às vezes, o log pode ser como um mapa do tesouro escondido!
