NoClassDefFound错误 [英] NoClassDefFound error

问题描述

java.lang.NoClassDefFoundError: javax/mail/Authenticator

我已经将激活器和邮件jar添加到我的服务器/ deps目录中，我仍然遇到这个问题，我不知道为什么。

I have added the activator and mail jars to my server/deps directory, and am still encountering this problem and I don't know why.

推荐答案

请记住 NoClassDefFoundError 与 ClassNotFoundException 不同。 NoClassDefFoundError 意味着在编译时在类路径中可用的类在运行时不可用。您确定您的jar文件位于运行时类路径？

Keep in mind NoClassDefFoundError isn't the same as ClassNotFoundException. NoClassDefFoundError means that a class that was available in the classpath at compile time isn't available at runtime. Are you sure your jar files are in the runtime classpath?
