构建后如何解决 'Xpage class could not be found'

Question

Xpages 应用已有几年历史，但现在，对现有 Xpage 的任何更新都会破坏它并显示浏览器消息：

HTTP Web Server: Item Not Found Exception

xpages_exec 日志显示：

com.ibm.xsp.page.PageNotFoundException: Could not create the page /Cards.xsp because the class xsp.Cards could not be found. Please check your spelling.

即使只是重新保存工作的 Xpage，也会发生这种情况；将不再找到 Xpage class。如果只是重命名或复制 Xpage，则相同。我在其他工作站上使用 Domino Designer 在服务器上得到了相同的结果。

也许这是 JVM 运行时间问题？服务器控制台显示 JVM 版本：

JVM: Java Virtual Machine initialized.
Java runtime version: 8.0.5.6 - pwa6480sr5fp6-20171124_02(SR5 FP6)
JVM version: JRE 1.8.0 Windows Server 2008 R2 amd64-64 20171122_371101 (JIT enabled, AOT enabled) OpenJ9 - 8e3c85d OMR - 713f08e IBM - c041ee8

Domino Designer Java 编译器工作区设置 JDK 合规级别设置为 1.5，安装了 JRE 1.6。

我如何确定为什么在新构建 Xpage 后导致 Xpage class 不再被发现？

更新：来自 xpages 执行日志：

在 Domino Designer 中，切换到 Package Explorer 视图，并查找任何错误。在上面的例子中，库 com.ibm.xsp.extlib.relational.library 包含在 xsp.properties 文件中但未找到。从 xsp.properties 中删除依赖项或确保库已安装或在构建路径中。
