java - Eclipse 无法启动

Question

当我尝试在 Windows 7 上启动 Eclipse Juno 时，会出现一个消息框，提示“发生错误。请查看日志文件”，并且 Eclipse 无法启动。我尝试重命名我的工作区文件夹或更改存储在 eclipse_root_folder\configuration.settings\org.eclipse.core.net.prefs 中的 eclipse 工作区设置，但它不起作用。我已经使用它 2 个月了，以前从未发生过这种情况。有什么解决办法吗？

• 我有最新版本的java
• /eclipsepath/eclipse.exe -clean [这不起作用]
• 我没有对我的电脑进行任何更改

Eclipse 将您的项目副本存储在它的缓存中。当 Eclipse 崩溃(发生)时，可能会发生此缓存已损坏的情况，因此 Eclipse 将无法再次启动。以“--clean”开头的 somethimes 解决了这个问题，但并非总是如此。

根据我的经验，一种解决方案是删除项目的缓存。在您的工作区中查找“.metadata”文件夹，并在 Eclipse 未运行时将其删除(进行备份以防万一)。然后再次启动 Eclipse。

您可能会丢失您的运行配置首选项，然后您可以从“.metadata/.plugins/org.eclipse.debug.core/.launches”的备份副本中恢复它。
