Eclipse 無法識別。java 文件

[英]Eclipse does not recognize .java files

 原文  2020-11-26 12:16:56  6   1    java/ eclipse/ exception/ resources/ bundle

問題描述

精簡版：

  • 無法啟動 eclipse
  • 刪除了一些快照和樹文件
  • 可以打開 eclipse 但找不到我的文件“無法確定 [項目名稱]/[文件路徑]/[文件名] 的 URI”
  • 無法重新導入它們，因為 Eclipse 無法識別。java 文件

長版：這一切都始於今天早上的這個錯誤消息（拿了最新的）：

這似乎導致了問題：
;MESSAGE 工作區退出，之前 session 中的更改未保存。 刷新工作區以恢復更改。

我通過刪除（和備份）.snap 和.tree 文件解決了這個問題：

這導致了我現在遇到的下一個問題。 我嘗試通過重新導入我的項目來解決這個問題，正如這篇文章中建議的“自鳴得意”：

順便提一句。 我將我的項目組織成 java 工作集。 不知道這是否有什么不同。
