我最近从 API 1.7 升级到 1.8.4，现在我无法部署...它卡住了，因为它找不到 jsp 正在使用的标签的类（标签和页面都没有改变很长时间）。
奇怪的是标签文件似乎已经被很好地拾取并且可以在暂存目录中找到（尽管它是那里唯一的文件 - 即使有很多标签）：
/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 Appengine Eclipse 插件，然后部署：
./appcfg.sh 更新 /Users/mauricio/Dev/sts5/warprod
（warprod 只是我整个项目 war 目录的副本 - 我这样做是为了在部署时可以继续处理项目）
这是错误：
