前言
经过上次安装YCM之后，发现不能支持java语言，于是自己摸索了一下，发现eclim能够和YCM配合起来使用，而需要的操作也是很少的。
工具
- YCM
- eclipse
- eclim
注意：eclim和eclipse的版本以及VIM的版本要对应，VIM 我的是7.4

安装
此处我们直接命令行安装
dream@love_lyy:~$ ./eclim_2.7.2.bin
Welcome to the installer for eclim 2.7.2.
# 选择eclipse的位置
Please specify the root directory of your eclipse install.
Ex: /opt/eclipse
/usr/local/eclipse
> /home/dream/eclipse/jee-oxygen/eclipse/
# 选择vim
Please specify the directory where you would like the eclim vimfiles installed.
If you do not want to install the vimfiles (eg: emacs-eclim users), then type: skip
Ex: ~/.vim
~/.vim/bundle/eclim
> /home/dream/.vim
Choose which eclim features you would like to install.
Type the number for each feature you want to install:
Ex (Java and Python): 0 5
Ex (Java and Python): 0,5
Ex (Java, Web, and C/C++): 0-2

-----------------------------------------
The eclim install completed successfully.
You can now start the eclimd server by executing the script:
/home/dream/eclipse/jee-oxygen/eclipse/eclimd
For more information please see the eclimd server documentation:
http://eclim.org/eclimd.html
For information on using eclim, please visit the getting started guide:
http://eclim.org/gettingstarted.html启动服务器
到这就搞定了，接下来是启动服务器
由于这个启动服务器的路径较长，我们在~/.bashrc里面最后一行添加别名
alias eclimd='/home/dream/eclipse/jee-oxygen/eclipse/eclimd'自己的eclipse目录/eclimd
检测
进入vim 在下面输入：PingEclim，出现下面的标记则视为成功
添加YCM配置
在vim配置中添加下面一句话就行了
let g:EclimCompletionMethod = 'omnifunc'问题解决方案
1、笔者在安装的过程中PingEclim失败了
解决：可能是Vim文件安装位置选择的时候，出现了问题
2、下载安装bin文件之后，执行不了
解决：修改chmod 777，因为没有执行权限
3、无法解析的主机
解决：修改host 127.0.1.1
dream@love_lyy:~/.vim/bundle$ cat /etc/hosts -n
1 127.0.0.1 localhost
2 127.0.1.1 dream-Lenovo-Y430P

4 # The following lines are desirable for IPv6 capable hosts
5 ::1 ip6-localhost ip6-loopback
6 fe00::0 ip6-localnet
7 ff00::0 ip6-mcastprefix
8 ff02::1 ip6-allnodes
9 ff02::2 ip6-allrouters

sudo: 无法解析主机：love_lyy最后附上Eclim指令集，话说VIM的简约风我很喜欢
