Eclipse Juno 加载描述符错误

Question

我刚刚将 Eclipse 从 Galileo 更新为 Juno。我创建了一个新的工作区并导入了一个基于 Java Spring MVC 的项目。当我打开它时，它开始“加载描述符”，然后弹出一条错误消息:“加载 mta_pfm 的描述符。”期间发生内部错误。如果我使用 Galileo 打开它，则不会出现错误。我尝试在 Juno 中禁用 XML 文件的验证，但它不起作用。我现在不知道如何解决它。请帮忙。谢谢

您的某些项目文件可能与 Juno 不兼容(Juno 在其第一个版本中不是很稳定，我建议下载官方更新补丁，甚至更好 - 迁移到感觉更可靠的 Kepler)。

无论如何，Eclipse 可以采用一些运行时参数，如下所述:http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html

编辑 Juno eclipse.exe 快捷方式并运行“'...\eclipse.exe' -clean”来刷新项目文件。

请记住在修复该参数后将其删除，因为您无需在每次启动 Eclipse 时清理项目文件。
