無法從Eclipse Oxygen工作區刪除項目

Question

嘗試從Eclipse Oxygen刪除項目時，沒有任何反應，並且在日志中寫入了異常。 我只需在包資源管理器中的項目上單擊鼠標右鍵，然后選擇“刪除”選項。 我正在使用Eclipse Oxygen.1a（4.7.1a）。 這是完整的構建信息：

Eclipse Platform
Version: Oxygen.1a (4.7.1a)
Build id: M20171009-0410
OS: Linux, v.4.13.0-19-generic, x86_64 / gtk 3.22.25

這是一個示例堆棧跟蹤：

任何想法如何解決這個問題？ 或任何解決方法？

Answer 1

由於我懷疑問題與GUI有關，因此我嘗試使用GTK 2而不是GTK 3運行eclipse。因此，我在eclipse.ini添加了以下幾行：

--launcher.GTK_version
2

問題解決了。 我可以再次刪除項目而沒有任何問題。
這是我完整的構建信息：

Eclipse Platform
Version: Oxygen.1a (4.7.1a)
Build id: M20171009-0410
OS: Linux, v.4.13.0-19-generic, x86_64 / gtk 2.24.31

Answer 2

這是一個已修復的錯誤（我猜是在氧氣中。3）。 這與解決“問題”圖標有關。 https://bugs.eclipse.org/bugs/show_bug.cgi?id=528984
