注： 不能用cmd 運行。具體的忘了。還要安裝sdkman。
1. sdk help 查看命令
2.sdk list java 查看java jdk
3.sdk install java 8.0.282.j9-adpt 安裝jdk 下邊有安裝命令提示。最后一欄是可選jdk版本
4.查看jdk安裝目錄
附加：遇到一個get請求參數問題，把&當成參數 & = %26。

把7-zip 的7z.exe 復制重命名到Git Bash下mingw\bin目錄下 不起作用。
沒辦法自能 照着教程
找到這個地址：https://sourceforge.net/projects/gnuwin32/files/
這里有很多支持的MinGW環境的軟件，搜索zip即可。
下載完zip-3.0-bin.zip之后，把里面的zip.exe復制到Git Bash下mingw\bin目錄下（根據自己的安裝目錄如：C:\softs\Git\mingw\bin，似乎放到usr\bin也可以）

因為curl無法驗證服務器提供的證書。
有兩個選項可以讓它發揮作用：
- 用卷曲連用
-k選項允許curl進行不安全連接，即curl不驗證證書。 - 將根CA(簽名服務器證書的CA)添加到
etc/ssl/certs/ca-certificates.crt
你應該使用選項2，因為這是確保連接到安全ftp服務器的選項。
將根CA(簽名服務器證書的CA)添加到etc/ssl/certs/ca-certificates.crt
Mac OS X 添加證書： sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/new-root-certificate.crt 移除證書： sudo security delete-certificate -c "<name of existing certificate>" Windows 添加證書： certutil -addstore -f "ROOT" new-root-certificate.crt 移除證書： certutil -delstore "ROOT" serial-number-hex Linux (Ubuntu, Debian) 添加證書： 復制 CA 文件到目錄： /usr/local/share/ca-certificates/ 執行: sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt 更新 CA 證書庫: sudo update-ca-certificates 移除證書： Remove your CA. Update the CA store: sudo update-ca-certificates --fresh Restart Kerio Connect to reload the certificates in the 32-bit versions or Debian 7. Linux (CentOs 6) 添加證書： 安裝 ca-certificates package: yum install ca-certificates 啟用dynamic CA configuration feature: update-ca-trust force-enable Add it as a new file to /etc/pki/ca-trust/source/anchors/: cp foo.crt /etc/pki/ca-trust/source/anchors/ 執行: update-ca-trust extract Restart Kerio Connect to reload the certificates in the 32-bit version.

Installing SDKMAN scripts...
Create distribution directories...
Getting available candidates...
Prime the config file...
Download script archive...
######################################################################## 100.0%
Extract script archive...
Install scripts...
Set version to 5.7.4+362 ...
Attempt update of interactive bash profile on regular UNIX...
Added sdkman init snippet to /c/Users/gary.fu/.bashrc
Attempt update of zsh profile...
Updated existing /c/Users/gary.fu/.zshrc
All done!
Please open a new terminal, or run the following in the existing one:
source "/c/Users/gary.fu/.sdkman/bin/sdkman-init.sh"
Then issue the following command:
sdk help
Enjoy!!!
現在重新打開一個Git Bash或者執行下面的命令就可以把sdkman加入到PATH中，然后就可以使用sdk命令了
source "$HOME/.sdkman/bin/sdkman-init.sh"
使用sdk version可以查看到sdk的版本了
sdk version
