company-emacs-eclim在項目中使用了錯誤的路徑

Question

對於大型的Java/Maven項目，我有一個新的Emacs設置（在Windows上）。

安裝了Eclipse和eclim（java層更新爲最新版本的spacemacs，作爲額外軟件包安裝的company-emacs-eclim），但是當company-emacs-eclim嘗試自動完成時，它使用錯誤的文件路徑插入該項目文件夾兩次，例如

X:/EclipseWorkspace/Project/Project/src/main/com/company/product/Klass.java 

，而不是

X:/EclipseWorkspace/Project/src/main/com/company/product/Klass.java 

錯誤消息

Company: An error occurred in auto-begin 
Company: backend company-emacs-eclim error "Could not read from "file:///X:/EclipseWorkspace/Project/Project/src/main/com/company/product/Klass.java" because it is a not a file." with args (candidates this) 

在eclimd，我得到同樣的消息的異常：

ERROR [org.eclim.command.Main] Command failed 
org.apache.commons.vfs.FileSystemException: Could not read from "file:///X:/EclipseWorkspace/Project/Project/src/main/com/company/product/Klass.java" because it is a not a file.

我試着關閉並重新打開工作區在Emacs中打開項目，重新創建整個工作區，所有內容都可以得到相同的結果。

Answer 1

簡短的回答似乎是eclim對多模塊maven項目的不完全支持。見例如https://github.com/ervandew/eclim/issues/499。

該問題與company無關，錯誤號碼相同，請致電eclim-complete。似乎發生的情況是，多模塊項目eclim--project-current-file被設置爲相對於根而不是當前項目的路徑。

您可以通過建議eclim--current-project-file返回正確的相對路徑來解決此問題。例如：

(defun my-eclim-fix-relative-path (path) 
    (replace-regexp-in-string "^.*src/" "src/" path)) 

(advice-add 'eclim--project-current-file :filter-return #'my-eclim-fix-relative-path) 

這可能會影響其他eclim的行爲，但在我的快速測試工作對我來說，當我工作的src/main和src /測試文件。

你檢查了項目根目錄下的.classpath文件的內容嗎？不知何故，這可能包含一些錯誤。如果將其編輯爲指向正確的目錄，則可能會修復自動完成。
