如何通过源码生成Gatling可执行工具
其实，这个对于不是很熟系sbt的人来说，或者对scala语言没有什么了解的人，接触Gatling这个开源的性能测试框架，还是有些茫然的。
因为GitHub上提供的Gatling （最新版本：2.2.0 snapshot）是源码，而且，完整的Gatling被拆分为Gatling（Core,相当于测试引擎吧）和Gatling-highchats（主要是用来生成测试报告）两部分。不知到为何要拆分为两部分，也许是因为Gatling-highchats部分引用了特殊license的软件插件（HighCharts & HighStock， 来自于HighSoft公司。。。)
1. 首先，从github上clone下gatling的源码。
git clone http://github.com/gatling/gatling
git clone http://github.com/gatling/gatling-highcharts
待这些文件都下载到本地后，先进入gatling的目录，在命令行下执行 sbt compile （，若你的系统下没有安装SBT，请先自己安装，我是直接在SBT官网下载的0.13.9的版本，解压到local目录下，再在/etc/profile下配置一下环境变量，方便使用）。gatling文件列表如下：
-rw-r--r-- root root Jan : CONTRIBUTING.md
drwxr-xr-x root root Jan : gatling-app
drwxr-xr-x root root Jan : gatling-bundle
drwxr-xr-x root root Jan : gatling-charts

drwxr-xr-x root root Jan : gatling-jdbc
drwxr-xr-x root root Jan : gatling-jms
drwxr-xr-x root root Jan : gatling-metrics
drwxr-xr-x root root Jan : gatling-recorder
drwxr-xr-x root root Jan : gatling-redis

drwxr-xr-x root root Jan : src
drwxr-xr-x root root Jan : target
-rwxr-xr-x root root Jan : trigger_build.py
-rw-r--r-- root root Jan : version.sbt
sbt compile执行完毕后(可能需要一段时间，因为有些依赖的库要下载)，需要将其发布到ivy仓库中（你也可以发布到mave仓库）:

这个过程，比较像mvn install将生成的模块安装到本地.m2仓库中的过程。到此，gatling引擎部分编译和发布完成。
然后，进入gatling-highchats,和上述编译gatling的过程类似，执行sbt compile，然后在发布到本地ivy仓库。注意，一定要先对gatling进行发布后再编译gatling-highchats，否则在编译gatling-highchats的时候会报错的，找不到依赖的库。
至此，编译部分都完成了，那么，问题来了，生成的工具（可执行文件）在什么地方呢？在什么地方可以执行刚才生成的工具呢？官网上说的比较清楚，我也倾向于用bundle的文件来执行。默认情况下，这个文件会在ivy的仓库里面。就拿我的环境来说,其目录如下：
[root@CloudGame zips]# pwd
/root/.ivy2/local/io.gatling.highcharts/gatling-charts-highcharts-bundle/2.2.-SNAPSHOT/zips
文件内容如下：
[root@CloudGame gatling-charts-highcharts-bundle-2.2.-SNAPSHOT]# ll
total
drwxr-xr-x root root Jan : bin
drwxr-xr-x root root Jan : lib
-rw-r--r-- root root Jan : LICENSE
drwxr-xr-x root root Jan : results
drwxr-xr-x root root Jan : user-files
[root@CloudGame gatling-charts-highcharts-bundle-2.2.-SNAPSHOT]# cd bin/

-rwxr--r-- root root Jan : gatling.sh
-rwxr--r-- root root Jan : recorder.bat
-rwxr--r-- root root Jan : recorder.sh
上面加黑的目录，就是我们想要的被解压后的目录，里面有我们期待的内容：
[root@CloudGame gatling-bundle-2.2.-SNAPSHOT]# ll
total
drwxr-xr-x root root Jan : bin
-rw-r--r-- root root Jan : LICENSE
drwxr-xr-x root root Jan : results
drwxr-xr-x root root Jan : user-files
[root@CloudGame gatling-bundle-2.2.-SNAPSHOT]# cd bin/
[root@CloudGame bin]# ll
total
-rwxr-xr-x root root Jan : gatling.bat
-rwxr-xr-x root root Jan : gatling.sh
-rwxr-xr-x root root Jan : recorder.bat
-rwxr-xr-x root root Jan : recorder.sh
到这里，可以说从源码生成gatling的过程结束了！
在此，我要说明一点就是，2.2.0-SNAPSHOT的版本，比较新，里面有些api是JDK8的，所以，在编译运行的时候，保证你的环境是jdk8哟，否则会出现下面的错误：
[root@CloudGame bin]# ./recorder.sh

最后，测试一下源码来的工具是否可用，哈哈，看到recorder的启动界面了，如下图，说明一切正常！
附加一下设置项目的javaHome的命令，即相关的操作！
