Eclipse Luna 的 Oracle Weblogic Server 插件启动错误

Question

我们有一个使用 Eclipse Indigo 和相关的 weblogic 服务器插件构建的现有项目。这是四年前完成的，我们正在尝试迁移到 Eclipse Luna。项目导入并且一切正常，直到我为 Eclipse Luna 或较低版本添加 weblogic 服务器工具插件并重新启动 eclipse。它开始抱怨 "An internal error occurred during"

构建工作区
初始化Java工具
验证项目
AppXray 索引（我可以通过禁用 Windows->Preferences->Oracle->AppXray 来解决这个问题）

生成的应用程序 EAR 部署在 Oracle Weblogic Server 10gR3 上。任何解决问题的帮助将不胜感激。我知道问题出在 Eclipse Luna 的 Oracle Weblogic Server 工具插件上，因为当我删除它时，我没有看到任何错误。我已经尝试清理 .metadata 然后重新启动 eclipse 但错误仍然开始出现。

UPDATE：下面是我从 .metadata 中的 .log 文件中发现的异常堆栈跟踪。我无法从日志中理解任何内容。有人可以帮忙吗？

Answer 1

在我们的团队遇到这个问题后，我想我会 post 我们找到的解决方案。

这发生在我们从基于 Luna 的 IDE 版本转移到 Mars SR1 版本时。我们追踪到源代码管理中的一个文件。

.settings/oracle.eclipse.tools.weblogic.syslib.xml

一旦删除，eclipse 就会愉快地启动，我们就可以开始了。一位开发人员将问题追溯到文件中的一行。

<module id="javax.persistence" javadoc="http://java.sun.com/javaee/5/docs/api"/>

如果注释掉那个行，eclipse oepe 错误就会消失。仅供参考，您在导入项目时不会看到此错误，只会在项目被拉下后的每次重新启动时看到。
