MELPA MELPA Stable Build Status


The JDEE is an add-on software package that turns Emacs into a comprehensive system for creating, editing, debugging, and documenting Java applications.

About the project

As of 2015-07-13, is the primary source repository.

Additional information can be found at and at


Emacs 24.3 is the oldest version that JDEE can be expected to run in.

JDEE requires JDEE Server for some operations.

Install from distribution

The project is available in MELPA.

For more information, see doc/install.html

Build from source options

  1. Run tests: make test

To use this built distribution without installation, in your .emacs add:

  (add-to-list 'load-path "/path/to/jdee")
  (require 'jdee)


Some of the features of JDEE include:

  • source code editing with syntax highlighting, auto indentation using the native GNU Emacs Java mode
  • Symbol completion (jdee-complete-in-line)
  • Code generation: templates, import insertion/deletion/ordering etc.
  • browse JDK doc, using the browser of your choice (jdee-help-symbol and jdee-help-docsets)
  • browse your source code (jdee-find-class* and semantic integration)
  • compilation with automatic jump from error messages to responsible line in the source code using ant (jdee-ant-build).
  • run Java application in an interactive (comint) Emacs buffer
  • integrated debugging with interactive debug command buffer and automatic display of current source file/line when stepping through code (jdee-debug)
  • supports Oracle/OpenJDK Java 7
  • runs on any platform supported by GNU Emacs 24.3 and later
  • easily and infinitely customizable

Known Issues

  • Static imports don't quite work
  • Limited support for Java template beyond basic highlighting, parsing, and indenting.
  • Indentation after multi-line annotations might be unexpected
  • It's a little crufty after all these years - patches welcome :-)



  • The mailing list is still hosted by sourceforge. It includes jdee-announce, jdee-users, and jdee-devel.
