我有一个项目要从 ANT 迁移到 Maven。 ANT 项目成功部署并运行。但是，当我尝试运行 mavenized 项目时，出现以下 JSP 编译错误：

我已经验证了战争中类存在，属性也存在。
【问题讨论】：
-
确保
TracingConstants类存在于war 项目的依赖库或您的war 项目中。另外，如果可以的话，stop using scriptlets at all. -
不确定你在说什么。我需要将其添加到清单的依赖项部分吗？
-
在 maven 中，您的 pom.xml 文件中有一个
<dependencies>部分。在那里，您应该为您的项目提供所有外部库。在其中一个库中，应该定义TracingConstants。确保你有必要的依赖。
