java - Emacs Java 马拉巴模式

Question

我在 Emacs 中为我的 java 项目使用 JDEE。 JDEE 不适用于 Maven。最近我遇到了 Malabar 模式，它更好地支持 Emacs 中基于 Maven 的 Java 项目。

我设法在 M-x list-packages 中使用 melpa 安装了 malbar-mode。但是当我在我的简单应用程序的 mvn package 上收到错误消息时 https://github.com/vijayendra/JavaSrc/tree/master/my-app

Projects.get('/home/egnyte/src/my-app/pom.xml', []).run(['package'], [], [:])

我的emacs版本如下:

emacs -version

我的.emacs文件如下:

(require 'package) ;; You might already have this line
(add-to-list 'package-archives
             '("melpa-stable" . "http://stable.melpa.org/packages/") t)
;; unstable packages
;; (add-to-list 'package-archives

  ;; For important compatibility libraries like cl-lib
  (add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/")))
(package-initialize) ;; You might already have this line

(require 'cedet)
(require 'semantic)
(load "semantic/loaddefs.el")
(semantic-mode 1)
(setq malabar-groovy-lib-dir "~/.m2/repository/com/software-ninja/malabar/1.5.10")
(require 'malabar-mode)
(add-to-list 'auto-mode-alist '("\\.java\\'" . malabar-mode))       

我的maven版本如下:

mvn -version
Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T13:58:10-07:00)

Default locale: en_US, platform encoding: UTF-8

我怎样才能让马拉巴尔模式工作？

Answer 1

有两个答案。

首先，malabar-mode 停留在 maven 3.0.4，所以请尝试该版本。也不要设置 lib 目录。它应该自动设置。

其次，为了避开 maven 版本，我从头开始重写 malabar-mode。按照 https://github.com/m0smith/malabar-mode/blob/develop/doc/2.0/INSTALL.md 上的说明进行操作.这个版本应该适用于 3.0.4 之后的所有版本的 maven。这是一项正在进行的工作，尚未提供所有功能。
如果您有问题或建议，请在 GitHub 存储库中创建问题，因为现在是表达您的愿望的好时机

编辑:malabar 2.0 已发布到 MELPA。现在安装:

```

(load-file "~/projects/cedet/cedet-devel-load.el")
(add-hook 'after-init-hook (lambda ()
             (message "activate-malabar-mode")
             (activate-malabar-mode)))

(add-hook 'malabar-java-mode-hook 'flycheck-mode)
(add-hook 'malabar-groovy-mode-hook 'flycheck-mode)

```
