配置参数注意：先—enable，后—with。弄错就make uninstall&&make clean&&重新配置编译安装。
vim-javacomplete2:
参考：https://unmi.cc/vim-java-autocomplete-with-vim-javacomplete2/#more-7708
这个网络资源不多，我简要说下。
1. 先安装 git 工具。
$sudo apt install git
2. 建立目录 ~/.vim/bundle (有了就跳过）
$mkdir ~/.vim/bundle -p
3. 进入目录
$cd ~/.vim/bundle
4. 下载 java-complete2
$git clone https://github.com/artur-shaik/vim-javacomplete2.git
参考上面的文章，
$cd vim-javacomplete2/libs/javavi/
$mvn compile
(没有maven就先安装。也把gradle安装了。网上自行下载配置环境变量，或者直接apt install）
5. 使用你的插件管理器管理 java-complete2 （最好看帮助文档）
修改 autoload/javacomplete/server.vim 191行，如下：
let command = ['mvn','-f','"'. javaviDir . 'pom.xml"','compile']
Factorus
1. 下载
$cd ~/.vim/bundle
$git clone https://github.com/apalmer1377/factorus.git
ale
参考：https://zhuanlan.zhihu.com/p/23317292
参考：http://blog.csdn.net/demorngel/article/details/69052789
1. 下载
$cd ~/.vim/bundle
$git clone https://github.com/w0rp/ale.git ./ale
2. 配置（看帮助文档）
其他的参考网络资源。
