参考

var fs = require('fs');
var path = "目标路径..";


function readDirectory(dirPath) {
    if (fs.existsSync(dirPath)) {
        var files = fs.readdirSync(dirPath);

改默认端口：

sudo vim /etc/gitlab/gitlab.rb
把external_url 改为 http://yourdomain.com:port

我在运行sudo gitlab-ctl reconfigure 之后查看gitlab status: sudo gitlab-ctl status 看到以下信息：

kymtwyf

  <excludeFromCompile>
    <file url="file://$PROJECT_DIR$/src/main/java/xxxController.java" />
  </excludeFromCompile>

由于误操作（我也不知道什么时候干的）发现这个 controller 下面的 api无法访问`No mapping found for HTTP request with URI /...` 
然后发现没有其他代码更变。只有一个在.idea 下面的 compiler.xml 里多了一句这个。手动删除却发现下次又生成了，所以查找了配置在(Preferences[command+,] -> Compiler ->Excludes ）下找到了。。。
