Answer 1

清理您的maven存储库：

（默认情况下在您的用户文件夹中）

~/.m2/repository

然后执行全新安装，以便再次下载依赖项并重新编译整个项目：

mvn clean install

Answer 2

ClassFormatError: Truncated class file

表示其中一个类文件已损坏。在运行clean目标之前，尝试运行install目标来执行错误的类清理。或者只是组合两个目标并为您的项目执行mvn clean install。

Answer 3

我可以从堆栈跟踪中看到您正在使用反射。当你正常使用它时，该课程是否正常工作？是否有可能在使用反射时，该类无法访问或被使用？

Answer 4

经过所有的研究和改变，我找到了解决方案，我更新了Maven依赖，它不起作用，

我卸载tomcat和Java然后重新安装它。

错误是Java Jdk因某些原因而被破坏我不知道为什么.....

并感谢您的所有建议
