> * I did not find JDEE in ELPA, MELPA, nor Marmalade. Why not add it to one of those?
The Java Development Environment for Emacs (JDEE) is an integrated development environment for Emacs. It interfaces Emacs to command-line Java development tools, for instance Sun’s JDK.
Development of JDEE is by all appearances slow. JDEE 2.4.1 was released in May, 2013 to support the latest CEDET version, but included no new features. Bug reports, patches, volunteers are very welcome! There was extensive discussion in April/May 2013 about a next generation JDEE (possible fork). Fortunately, there are signs of development for Java in CEDET. For an other alternative see EmacsEclim which provides Eclipse-like features for Java development.
Project site: http://jdee.sourceforge.net/
As of JDEE version 2.4.1, JDEE works with CEDET that comes with Emacs 24.3 release (and is known to work with Emacs 23.4 or later).
If you download the binary at http://sourceforge.net/projects/jdee/files/jdee/2.4.1/ there is no other dependency to mention.
If you checkout from the Svn repo, ant and ant-contrib are dependencies to build. Svn repo: https://jdee.svn.sourceforge.net/svnroot/jdee/trunk
There’s no obvious way to submit a bug at the SourceForge? page. Perhaps it requires an account. This section aggregates bug reports from those who don’t want to create an account.

As of 2013-06-14, Emacs 24.3 and JDEE 2.4.1 are latest releases. This JDEE release will work with Emacs 23.4 or later. See Download section above to obtain JDEE.
Next all you need in your init file is something like:
(add-to-list 'load-path (format "%s/dist/jdee-2.4.1/lisp" my-jdee-path)) (autoload 'jde-mode "jde" "JDE mode" t) (setq auto-mode-alist (append '(("\\.java\\'" . jde-mode)) auto-mode-alist))
See http://jdee.sourceforge.net/install.html for more details.
Download CEDET 1.1 and load it in Elisp. Emacs comes with CEDET 2.0; you must load CEDET 1.1 before other packages load the version in Emacs. Older JDEE are not compatible with new CEDET.
When downloading the prebuilt older release, you’ll need some Elisp to prevent fatal errors:
(setq jde-check-version-flag nil) (define-obsolete-function-alias 'make-local-hook 'ignore "21.1") (unless (fboundp 'semantic-format-prototype-tag-java-mode) (defalias 'semantic-format-prototype-tag-java-mode 'semantic-format-tag-prototype-java-mode)) (require 'hippie-exp)
Use something like this to load JDEE for .java files:
(add-to-list 'load-path (format "%s/lisp" "~/.emacs.d/jdee-188.8.131.52" "Path to JDEE")) (autoload 'jde-mode "jde" "JDE mode." t) (setq auto-mode-alist (append '(("\\.java\\'" . jde-mode)) auto-mode-alist))
JDEE 184.108.40.206 was confirmed to work in the 24.2.90 pretest release with this approach.
See also: http://forums.fedoraforum.org/showthread.php?t=280711 . Note that editing jde.el and deleting jde.elc is not necessary when setting jde-check-version-flag per above.
If you are using Emacs 23.4 or later use use the latest release (JDEE 2.4.1) without external dependencies as described above.
Install notes for Gnu Emacs 23 and earlier JDEE releases below. This will help you get (require ‘jde) running. No guarantee on anything else.
jde depends: cedet, elib.
(add-to-list 'load-path "/usr/share/emacs/site-lisp/cedet-common/") (add-to-list 'load-path "/usr/share/emacs/site-lisp/cedet-contrib/") ;;for jde (require 'cedet) (add-to-list 'load-path "/usr/share/emacs/site-lisp/elib/")
Then you need to edit jdel.el in lisp dir.
Remove or comment out the following lines, because autoload is now part of emacs, and there is no jde-autoloads.el in jde src.
(require 'jde-autoload) .... (unless (and jde-xemacsp (file-exists-p (expand-file-name "jde/auto-autoloads.el" (jde-root)))) (require 'jde-autoload))
For jde itself, add these to .emacs, change the dirs to fit your install of course:
;;-------------------- ;; jde (add-to-list 'load-path "~/.emacs.d/jde-current/") (require 'jde) (setq jde-web-browser "firefox") (setq jde-doc-dir "~/d/jdk-6-doc/")
I don’t know much about it myself. I guess there are more problems waiting.
How to load JDE in Emacs >=23.2 (after CEDET integration into Emacs trunk):
Use the latest release, JDEE 2.4.1! For prior JDEE releases:
I fear it is complex, as the CEDET inclusion changed package names but JDEE is still using the old ones (tested in branches 2.4 and trunk). For instance (require ‘semantic-ctxt) is the old name (standalone CEDET), but in the Emacs-included CEDET it should be transformed to (require ‘semantic/ctxt). Someone must update JDEE. 24.m3.2010, DanielClemente
I finally got JDE to work (mostly) with emacs 23.2. Here is what I did:
1) Download trunk source from svn. 2) Extract the source 3) ant configure 4) ant
here is my init file… There a few ‘tricks’ in here:

Note from 2004: If you use the Debian Sid jde package with CVS Emacs, you may need to apply this patch.
Did you install it correctly as documented? The website says: “Nearly all the JDEE problems that I have seen are caused by faulty setups,” and “Most problems reported by users are installation/setup problems.” See the Trouble Shooting Guide (Dead link).
