Java 部署到appengine时Jsp编译期间发生ClassNotFoundException

我最近从API 1.7升级到1.8.4，现在我在部署方面遇到了问题。。。它被卡住了，因为它找不到jsp正在使用的标记的类（标记和页面在很长一段时间内都没有改变）

奇怪的是，标记文件似乎被很好地提取出来，并在staging目录中找到（尽管它是那里唯一的文件-尽管有许多标记）：

/private/var/folders/vf/5yfk4j290xd3l09yrkq9vf_m0000gn/T/1382335959467-0/org/apache/jsp/tag/web/util/panel_tagx.java

我没有使用maven或ant，只是使用Appengine Eclipse插件，然后使用以下工具进行部署：

./appcfg.sh更新/Users/mauricio/Dev/sts5/warpsrod

（warprod只是我整个项目war目录的一个副本-我这样做是为了在部署时继续处理项目）

以下是错误：

提前谢谢

您是否从类路径中删除了旧的jar并添加了新的jar？我在依次删除每个jar时进行了尝试，如果只删除datanucleus-enhancer-1.1.4.jar，它就会部署，但在运行时，它会抱怨类没有得到增强（我不知道是否需要jar，或者增强功能是否已经损坏）。我还尝试使用1.7部署与1.7完全相同的先前代码库，无论是否使用dn enhancer jar，它都可以正常工作。对不起，回复太慢了。
