是否有人能够成功安装Oracle Enterprise Pack for Eclipse和Liferay IDE?似乎有一个相互排斥的依赖蓝宝石的东西，我找不到一个hack安装两个。
下面是Eclipse在尝试安装Liferay IDE时给出的错误:
Cannot complete the install because of a conflicting dependency.
Software being installed: Liferay IDE 1.3.1.v201108310601 (com.liferay.ide.eclipse.tools.feature.group 1.3.1.v201108310601)

最新版本的Liferay IDE需要一个特定版本的Sapphire才能运行，因此它不能与Oracle共同安装，Oracle也需要一个不同的特定版本。
唯一的解决方法是下载Liferay IDE源代码并手动构建它，在构建它之前，打开所有下载Liferay IDE插件(其中5个有蓝宝石深度)上蓝宝石要求的有效版本范围。注意:这意味着任何时候Liferay IDE中基于蓝宝石的功能实际上击中了需要的东西，它可能会失败，但其他一切都会正常工作。如果您对解决这个问题感兴趣，我很乐意提供帮助，但我们应该在这里继续对话:Liferay IDE论坛
我找到解决办法了。先安装oracle包，再安装liferay Ide插件。
