java - Jdeveloper 启动时错误 "java.lang.NoClassDefFoundError: Could not initialize class oracle.dbtools.raptor.config.DBConfig"

Question

我使用的是 Jdeveloper Studio 11.1.1.4.0，我在上面使用了 ADF 组件，但是最近几天当我启动 Jdeveloper 时，出现了这个错误

Uncaught exception
java.lang.NoClassDefFoundError: Could not initialize class oracle.dbtools.raptor.config.DBConfig

我也找不到数据库导航器，当我使用与数据库相关的任何东西时也会出现此错误，我尝试卸载 Jdeveloper 并删除中间件文件夹并重新安装所有内容以获取默认但仍然是同样的故事.

我真的需要尽快解决这个问题，因为我的毕业设计已经落后于计划。

谢谢。

检查你的类路径，肯定是这里有问题，验证JDeveloper文件夹在
