company-emacs-eclim 使用错误的项目路径
company-emacs-eclim uses wrong path for project
我有一个新的 Emacs 设置（在 Windows 上）用于一个大型 Java/Maven 项目。
安装了 Eclipse 和 eclim（带 java 层的 spacemacs 更新到最新版本，company-emacs-eclim 作为额外包安装），但是当 company-emacs-eclim 尝试自动完成时，它使用了错误的路径到文件，两次插入项目文件夹，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
错误信息是
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 中，我得到一个异常并显示相同的消息：
ERROR [org.eclim.command.Main] Command failed

我试过关闭并重新打开工作区，在 Emacs 中重新打开项目，重新创建整个工作区，一切都得到相同的结果。
您是否检查过项目根目录下的 .classpath 文件的内容？这可能以某种方式包含一些错误。如果您编辑它以指向正确的目录，这可能会修复自动完成。
简短的回答似乎是 eclim 对 multi-module maven 项目的支持不完整。参见例如https://github.com/ervandew/eclim/issues/499.
问题与 company 无关，错误与调用 eclim-complete 相同。似乎发生的是在 multi-module 项目中 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 到 return 正确的相对路径来解决这个问题。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 行为，但在我的快速测试中，当我处理 src/main 和 src/test 文件时它对我有用。
