Question

我在Emacs中使用JDEE作为我的java项目。 JDEE对maven不起作用。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malbar-mode。但是当我在mvn package上收到针对我的简单应用https://github.com/vijayendra/JavaSrc/tree/master/my-app

的错误消息时

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

(require 'cedet)
(require 'semantic)
(load "semantic/loaddefs.el")
(semantic-mode 1)

(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)

如何让malabar模式起作用？

Answer 1

有两个答案。

首先，malabar-mode停留在maven 3.0.4，所以试试那个版本。也不要设置lib目录。它应该自动设置。

其次，为了绕过maven版本，我将从头开始重写malabar-mode。按照https://github.com/m0smith/malabar-mode/blob/develop/doc/2.0/INSTALL.md上的说明操作。此版本应适用于3.0.4之后的所有版本的maven。这是一项正在进行的工作，并不是所有的功能都在那里如果您有问题或建议在GitHub仓库中创建问题，因为现在是了解您的愿望的好时机

编辑：马拉巴尔的2.0已经发布给MELPA。立即安装：

```

(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)

```
