netty作为异步通信底层框架，其优异的性能让我产生了研究他的源码的决定。
代码研究之前，第一步就是要准备环境，至少可以编译通过，下面，就拿github上的4.1分支进行。我的IDE是Intellij IDEA 2016 community版本， 操作系统是Windows 7。
一开始，就踩雷了，起初，我的源码是在Github上，通过zip的方式获取4.0分支的代码，编译的时候，总是报错。各种line endings的错误，日志如下：

后来在各种搜索中找解决方案，百度中很多地方的帖子都说是maven的plugin配置的问题，后来我依着提示修改，然并卵。 最后在stackoverflow上找到一个帖子的建议链接，链接如下：https://help.github.com/articles/dealing-with-line-endings/#platform-windows
里面说的很清楚：
When you view changes in a file, Git handles line endings in its own way. Since you're collaborating on projects with Git and GitHub, Git might produce unexpected results if, for example, you're working on a Windows machine, and your collaborator has made a change in OS X.
不同的人在不同系统上提交的代码，对文件行的处理方式不一样，比如换行，windows下是/r/n，但是linux下换行是/n。
解决方案，我采用的是他的第一个解决方案：
Global settings for line endings
The
git config core.autocrlfcommand is used to change how Git handles line endings. It takes a single argument.On Windows, you simply pass
trueto the configuration. For example:git config --global core.autocrlf true # Configure Git on Windows to properly handle line endings
执行后，在window下，CMD里面执行git clone取代码4.1的代码。习惯了linux下的操作，用git@github.com:netty/netty.git，结果出错，因为我windows上没有ssh的key。。。改用https的地址clone就可以了，如下图：
代码获取了，此时的代码，应该不会再有line endings的错误了吧，继续在IJ里面编译试试：
这次编译，终于可以了，没有什么问题。
这次git的这个问题，让我还折腾了不少时间，因为Intellij报的错误的确是说checkStyle的问题，找plugin的问题，没有想到是github上的代码因为git处理core.autocrlf的策略问题，默认git中的配置，这个参数是false，改成true后，git取源码再编译，就ok了。
上面的处理，是编译其中一个模块，netty-common，现在，我们要编译整个工程，就是netty的根工程，让所有的模块都编译通过。
这里，说说Intellij中如何用maven编译代码，如我上面的截图中出现右边的Maven projects这个框，若不是很熟悉Intellij的伙伴，比如老是用Eclipse的人，可能真不知道如何打开这个窗口。其实很简单：
在菜单栏中： view->Tool windows->Maven Projects
另外，在这Maven Projects的操作面板上，有几个小button，我喜欢在Install或者Package的时候，不要test这个lifecycle，点击一下skip test即可。
是不是test上有一个删除线了。。。。
下面看看整个工程的编译安装，即mvn install的操作。
一切都ok了，install的操作完美收官！
若是想在windows下通过Intellij IDEA对netty的源码进行编译的话，本帖子可以给你提供一点借鉴，欢迎转帖。转帖请指明出处。
