记录sdkman 安装jdk

注： 不能用cmd 运行。具体的忘了。还要安装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   安装jdk   下边有安装命令提示。最后一栏是可选jdk版本

4.查看jdk安装目录  

 附加：遇到一个get请求参数问题，把&当成参数  & = %26。

 软件：(好用的)综合性桌面搜索软件(支持xp、win7、win8、win10及macOS系统)->火萤酱

idea  ctrl+shift+F9  重新加载.java文件，不需要重启项目。MobaXterm 终端工具。

把7-zip 的7z.exe 复制重命名到Git Bash下mingw\bin目录下 不起作用。

没办法自能 照着教程

找到这个地址：https://sourceforge.net/projects/gnuwin32/files/

这里有很多支持的MinGW环境的软件，搜索zip即可。

下载完zip-3.0-bin.zip之后，把里面的zip.exe复制到Git Bash下mingw\bin目录下（根据自己的安装目录如：C:\softs\Git\mingw\bin，似乎放到usr\bin也可以）

2.在运行

curl -s "https://get.sdkman.io" | bash

遇到curl SSL问题

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

因为curl无法验证服务器提供的证书。

有两个选项可以让它发挥作用：

1. 用卷曲连用-k选项允许curl进行不安全连接，即curl不验证证书。
2. 将根CA(签名服务器证书的CA)添加到etc/ssl/certs/ca-certificates.crt

你应该使用选项2，因为这是确保连接到安全ftp服务器的选项。

将根CA(签名服务器证书的CA)添加到etc/ssl/certs/ca-certificates.crt

Mac OS X
添加证书：

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/new-root-certificate.crt

移除证书：

sudo security delete-certificate -c "<name of existing certificate>"

Windows
添加证书：

certutil -addstore -f "ROOT" new-root-certificate.crt

移除证书：

certutil -delstore "ROOT" serial-number-hex

Linux (Ubuntu, Debian)
添加证书：

复制 CA 文件到目录： /usr/local/share/ca-certificates/

执行:

sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt

更新 CA 证书库:

sudo update-ca-certificates

移除证书：

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)
添加证书：

安装 ca-certificates package:

yum install ca-certificates

启用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/

执行:

update-ca-trust extract

Restart Kerio Connect to reload the certificates in the 32-bit version.

地址不稳定可以多跑几遍安装成功是这样子的

######################################################################## 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!!!

现在重新打开一个Git Bash或者执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
