概述
从官方给出的安装说明，我们可以知道，官方给出的安装脚本是基于脚本https://get.sdkman.io/进行安装的，下面是该脚本的全部内容。

脚本下载文件https://api.sdkman.io/2/broker/download/native/install/0.4.6/linuxx64重命名为sdkman-native-版本号.zip，比如sdkman-native-0.4.6.zip，将其解压后的内容复制放到~/.sdkman目录。
- 生成一个文件内容
export SDKMAN_SERVICE="https://api.sdkman.io/2"
export SDKMAN_VERSION="5.18.2"
export SDKMAN_NATIVE_VERSION="0.4.6"
# ...
echo "Getting available candidates..."
SDKMAN_CANDIDATES_CSV=$(curl -s "${SDKMAN_SERVICE}/candidates/all")
echo "$SDKMAN_CANDIDATES_CSV" > "${SDKMAN_DIR}/var/candidates"
脚本访问服务https://api.sdkman.io/2/candidates/all，将其返回值用于生成文件~/.sdkman/var/candidates
想法
考虑到sdkman官方服务部署在海外，有时候访问不了，我们这里可以通过其他手段将这三个文件提前下载下来，基于nginx部署为本地服务，并将服务地址指向本地服务，这样后续安装的时候，就不在受到海外服务卡顿带来的影响了。
下面是我基于官方脚本重新修改后的安装脚本，内容如下

cat sdkman.sh | bash
