println "signfile:"+System.getenv("PS1")      
properties.load(project.rootProject.file(System.getenv("qssqsignfile")).newDataInputStream())

发现无论是系统的还是 用户目录下的环境变量~/.bash_profile的都获取为null,下面

curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync-now -o ~/bin/osx-env-sync-now
如果~/bin目录不存在，则mkdir创建一个便是，或者使用系统的bin文件夹也行。
给脚本权限
chmod +x ~/bin/osx-env-sync-now

在需要重新加载脚本的时候执行命令

但是我发现我这里是不生效的。

那么改成这样吧

```curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync-now -o /bin/osx-env-sync-now```
```osx-env-sync-now```
发现不行的.

aaadeMBP:bin aaa$ curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync-now -o /usr/local/bin/osx-env-sync-now

/Users/aaa/Library/LaunchAgents/osx-env-sync.plist: No such file or directory
Environment variables reloaded. Now relaunch your GUI apps to make them aware.
For command line apps, launch a new Terminal session.
aaadeMBP:bin aaa$

ok

curl https://raw.githubusercontent.com/ersiner/osx-env-sync/master/osx-env-sync-now -o /usr/local/bin/qssq-env-sync

然后```chmod /usr/local/bin/qssq-env-sync```
然后 ```chmod qssq-env-sync```
唉。

最后这篇文章更靠谱s
也就是编辑```/etc/profile```环境变量文件，首先要```sudo chmod 777 /etc/profile```让自己可以修改文件，然后 ```vim /etc/profile```

signfile=/Users/aaa/Documents/qssq.keysotre
qssqsignfile=/Users/aaa/Documents/qssq.keysotre
launchctl setenv signfile $signfile
launchctl setenv signfile $qssqsignfile

然后重启

最后发现还是不行，好吧，还是每次重启电脑手动启动批处理
各位知道mac电脑能有效设置自启动的留言下，反正上面的命令启动似乎没效果，我也不知道如何查询到底是啥导致没效果。

#!/bin/bash
qssq-env-sync
echo 环境变量已经设置完成

手痒百度了一下添加自启动。

我的方法是给批处理脚本可执行权限，然后添加这个批处理自启动，这样不需要每次电脑开机启动就要手动执行一次命令了。
