这是报错信息。

问题是，我两个Process文件里面都有一个OnBeforeStart事件，事件里面代码都是一样的，引用得类也是一样的，结果一个报了找不到类的错，另一个不报错。

1. import utility.ProcessEvent;
   
2. 
   
3. public class Reject02Process {
   
4. 
   
5.         public static void reject02ProcessBeforeStart() {
   
6.                 ProcessEvent.processBeforeStart();
   
7.         }
   
8. }

复制代码

1. import utility.ProcessEvent;
   
2. 
   
3. public class Reject01Process {
   
4. 
   
5.         public static void reject01ProcessBeforeStart() {
   
6.                 ProcessEvent.processBeforeStart();
   
7.         }
   
8. }

复制代码

在源码路径下，两个java文件都是不报错的。。

确认model.config.xml中引用java类所在的路径了吗？
