company-emacs-eclim在项目中使用了错误的路径

Question

对于大型的Java/Maven项目，我有一个新的Emacs设置（在Windows上）。

安装了Eclipse和eclim（java层更新为最新版本的spacemacs，作为额外软件包安装的company-emacs-eclim），但是当company-emacs-eclim尝试自动完成时，它使用错误的文件路径插入该项目文件夹两次，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 

错误消息

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，我得到同样的消息的异常：

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.

我试着关闭并重新打开工作区在Emacs中打开项目，重新创建整个工作区，所有内容都可以得到相同的结果。

Answer 1

简短的回答似乎是eclim对多模块maven项目的不完全支持。见例如https://github.com/ervandew/eclim/issues/499。

该问题与company无关，错误号码相同，请致电eclim-complete。似乎发生的情况是，多模块项目eclim--project-current-file被设置为相对于根而不是当前项目的路径。

您可以通过建议eclim--current-project-file返回正确的相对路径来解决此问题。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) 

这可能会影响其他eclim的行为，但在我的快速测试工作对我来说，当我工作的src/main和src /测试文件。

你检查了项目根目录下的.classpath文件的内容吗？不知何故，这可能包含一些错误。如果将其编辑为指向正确的目录，则可能会修复自动完成。
