Emacs Java Malabar模式

Question

我在Emacs中的java项目中使用JDEE。JDEE在maven上不能很好地工作。最近我遇到了Malabar模式，它对Emacs中基于Maven的Java项目有更好的支持。

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

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

我的emacs版本如下：

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
;;              '("melpa" . "http://melpa.org/packages/") t)

  ;; 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)

我怎样才能让malabar模式工作？

Answer 1

有两个答案。

首先，malabar-mode停留在maven 3.0.4上，所以尝试一下这个版本。另外，不要设置lib目录。它应该自动设置。

其次，为了绕过maven版本，我从头开始重写了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。此版本应适用于maven 3.0.4之后的所有版本。这是一项正在进行的工作，并不是所有的功能都在那里。

如果您有问题或建议，请在GitHub资源库中创建一个问题，因为现在是了解您的愿望的好时机

编辑: malabar的2.0版本已经发布到MELPA。要立即安装：

```javascript

(加载文件"~/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)
