Java ANT脚本无法在web应用程序的lib文件夹中找到jstl-1.2.jar

我试图通过ANT脚本运行我的web应用程序，但在尝试运行它时出现以下错误：

我知道这个错误是由于web应用程序的lib文件夹中缺少jstl-1.2 jar造成的。我已经把它放在那里了

即使应用程序在Eclipse上也运行得很好，但当我在Eclipse中通过ANT脚本运行它时，它会抛出一个异常，如上所述

我不明白为什么ANT脚本找不到jstl-1.2.jar

这是我的ANT脚本：

将war部署到服务器中。。
编译。。。
WAR文件是为给定项目创建的！！！
服务器已启动。。
服务器已停止。。
执行

尝试打开.war文件，例如使用WinZip，查看它是否实际包含.jar文件。我的war文件包含每个jar文件的两个副本。虽然它确实包含jstl.jar，并且从中提取出来的文件夹只包含一个jar。javax.faces.Thancing@Andreas，我刚刚删除了Tomcat的webapps中的WAR和文件夹，并再次运行了脚本。它正在工作！尝试打开.war文件，例如使用WinZip，查看它是否实际包含.jar文件。我的war文件包含每个jar文件的两个副本。虽然它确实包含jstl.jar，并且从中提取出来的文件夹只包含一个jar。javax.faces.Thancing@Andreas，我刚刚删除了Tomcat的webapps中的WAR和文件夹，并再次运行了脚本。它正在工作！
