每次我尝试刷新 Hibernate 逆向工程文件的数据库方案时，都会收到未处理的事件循环异常：

但是，我将 commons-collections-3.2.2.jar 和 commons-collections-3.2.2-javadoc.jar 放在 Build Path 中，所以在 WebContent/WEB-INF/lib 中：Project Explorer

有人知道如何解决这个问题吗？

【问题讨论】：

有同样的问题。尝试卸载并重新安装插件。类似于***.com/questions/36827726/…，但答案不起作用。它正在hibernate.atlassian.net/browse/HBX-1256

进行跟踪

【参考方案1】：

我已经通过 Hibernate Console Configuration 将 hibernate 版本降级到 4.3 并创建了配置（Hibernate Perspective - Run Hibernate - Hibernate Code Generation Configuration），它开始工作了。

【讨论】：

好吧终于找到了。只需右键单击并在休眠透视图中“编辑配置”
