參照官網：https://github.com/shyiko/jabba
window 10：powershell下執行
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Invoke-Expression (
Invoke-WebRequest https://github.com/shyiko/jabba/raw/master/install.ps1 -UseBasicParsing
).Content
問題1：
Invoke-WebRequest : 未能解析此遠程名稱: 'raw.githubusercontent.com'

解決：
1）打開IPAddress.com網站，輸入raw.githubusercontent.com，查詢出結果，如下：
Hostname Summary
Domain githubusercontent.com
IP Address
199.232.68.133
Web Server Location United States
2）在C:/Windows/System32/drivers/etc/hosts中添加
199.232.68.133 raw.githubusercontent.com
問題2：

最后輸入Y。
2.使用
常用命令可參照官網：https://github.com/shyiko/jabba
問題1：將系統中已安裝的JDK鏈接到jabba中
jabba link system@1.8.171 C:\Program Files\Java\jdk1.8.0_171
C:\Program\bin\java.exe wasn't found. If you believe this is an error - please create a ticket at https://github.com/shyiko/jabba/issues (specify OS and command that was used)
解決：由於路徑中有空格，將Program Files改為縮寫Progra~1
jabba link system@1.8.171 C:\Progra~1\Java\jdk1.8.0_171
問題2：將系統中已安裝的JDK鏈接到jabba中
jabba link system@1.8.171 C:\Progra~1\Java\jdk1.8.0_171
symlink C:\Progra~1\Java\jdk1.8.0_171 C:\Users\sanpingx\.jabba\jdk\system@1.8.171: A required privilege is not held by the client.
解決：權限不夠，以管理員身份運行power shell
