记录一次GoCD的报错：The following option

今天发现一款和Jenkins类似的持续交付系统，决定安装来试一试。官方提供了免安装的zip版，不过我不想去弄jre，于是直接用 7Zip 解压从官网下载的exe安装包来用。GoCD 的agent，不论是直接打开 bin 目录下的 go-agent.bat 还是使用 install-go-agent-service.bat 来安装服务，都启动不了，都提示下面的错误：

经过一番查找，原来是要加 -serverUrl 参数来指定 GoCD server 的地址：

# 安装服务时设置 GoCD server 的地址
bin\install-go-agent-service.bat -serverUrl http://127.0.0.1:8153/go

当然，如果嫌麻烦的话，还是直接用exe来安装吧，安装的过程中会有 GoCD server 地址的配置：
