emacs自动完成不适用于jde

Question

我想用emacs开发java。我安装了欧洲央行，jde和自动完成的扩展。每个人都工作得很好，而没有开始其他人。但是当我想把它们放在一起的时候，发生了一些问题。

1. 自动完成模式不是用jde自动启动的，我需要通过M自动完成模式启动它.如果没有jde，自动完成模式将自动启动。
2. 当我在jde中手动启动自动完成模式时，自动完成不能正常工作.它只会自动完成出现的单词。

以下是我的.emacs内容：

(global-linum-mode 1)
(setq linum-format "%2d| ")

(setq default-tab-width 4)

(setq debug-on-error t)

;;no backup file
(setq make-backup-files nil)

(setq debug-on-error t)

;;auto complete config
(add-to-list 'load-path "D:/emacs-24.1/custom_el/auto-complete-1.3.1")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "D:/emacs-24.1/custom_el/auto-complete-1.3.1/dict")
(ac-config-default)

(setq stack-trace-on-error t)

(add-to-list 'load-path (expand-file-name "D:/emacs-24.1/custom_el/jdee-2.4.0.1/lisp"))
(add-to-list 'load-path (expand-file-name "D:/emacs-24.1/custom_el/cedet-1.1/common"))
(add-to-list 'load-path (expand-file-name "D:/emacs-24.1/custom_el/elib-1.0"))

(add-to-list 'load-path'  "d:/emacs-24.1/custom_el/ecb-2.40")


;; Initialize CEDET.
(load-file (expand-file-name "D:/emacs-24.1/custom_el/cedet-1.1/common/cedet.el"))
(load-file (expand-file-name "D:/emacs-24.1/custom_el/ecb-2.40/ecb.el"))


(require 'ecb)
(ecb-activate)
(ecb-byte-compile)


;; If you want Emacs to defer loading the JDE until you open a 
;; Java file, edit the following line
(setq defer-loading-jde nil)
;; to read:
;;
;;  (setq defer-loading-jde t)
;;

(if defer-loading-jde
    (progn
      (autoload 'jde-mode "jde" "JDE mode." t)
      (setq auto-mode-alist
        (append
         '(("\\.java\\'" . jde-mode))
         auto-mode-alist)))
 (require 'jde))


;; Sets the basic indentation for Java source files
;; to two spaces.
(defun my-jde-mode-hook ()
  (setq c-basic-offset 2))

(add-hook 'jde-mode-hook 'my-jde-mode-hook)

(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(ecb-options-version "2.40")
 '(ecb-primary-secondary-mouse-buttons (quote mouse-1--C-mouse-1)))
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )

版本信息是：

emacs : 24.1
auto complete : 1.3.1
ecb : 2.40
cedet : 1.1
elib : 1.0
jdee : 2.4.0.1

要用jde-mode自动启动jde-mode，需要将jde-mode添加到ac-modes中。

(push 'jde-mode ac-modes)

然后，您需要向ac-sources添加特定于JDEE的源代码。我不确定JDEE与语义的集成程度，您可能可以使用预定义的源代码：

(add-hook 'jde-mode-hook (lambda () (push 'ac-source-semantic ac-sources)))

如果不是，您可能需要用ac-define-source定义一个专门的源。有关示例，请参见auto-complete-config.el。
