This is a few helpers for using compilation mode in Emacs with maven.
If your maven is in a nonstandard location, (setq mvn-command "/path/to/ant -emacs")
If your build doesn't use "pom.xml", you'll need to modify mvn-command to end with with -f or --file and also do (setq mvn-build-file-name "somethingelse.xml") so that the automated project root discovery works correctly.
Put mvn.el in your load-path and add (require 'mvn) to your .emacs
The basic operation is to invoke M-x mvn, which will ask you for a goal.
M-x mvn-last will re-issue the last command
M-x mvn-compile will run the standard mvn compile
M-x mvn-clean will run the standard mvn clean
M-x mvn-test will run the standard mvn test
mvn can be called non-interactively too, in which case it's called as such: (mvn "sometask"). This means that you can can define your own functions like mvn-compile for your projects:
(defun mvn-compile-full ()
(interactive)
(mvn "dependency:sources"))
M-x mvn-kill-cache kills the internal cache used to speed up the auto-completion of ant tasks in the mini-buffer.
When the compilation buffer looks garbled, it usually from the wrong terminal escape sequences. You may insert following code into your init script so that compilation buffer can correctly shows colored messages ansi-color:
(ignore-errors
(require 'ansi-color)
(defun colorize-compilation-buffer ()
(when (eq major-mode 'compilation-mode)
(let ((inhibit-read-only t))
(if (boundp 'compilation-filter-start)
(ansi-color-apply-on-region compilation-filter-start (point))))))
(add-hook 'compilation-filter-hook 'colorize-compilation-buffer))
In the future, I'd really like to build a more general mode for working with Java code--something like malabar-mode, but without a lot of the semantic stuff it does. Minimal requirements:
1. It needs to support navigation really well (jtags does a decent to good job here)
2. It needs to be able to find code in source jars (if available)
3. It needs to have a built in way to launch a REPL (clojure, jython, sisc) for experimental programming purposes
4. Run test at point/file
5. List possible maven goals
