Extract script archive...
Install scripts...
Set version to 5.5.9+231 ...
Updated existing /Users/aven/.bashrc
Attempt update of zsh profiles...
Updated existing /Users/aven/.zshrc
All done!
Please open a new terminal, or run the following in the existing one:
source "/Users/aven/.sdkman/bin/sdkman-init.sh"
Then issue the following command:
sdk help
Enjoy!!!然后根据命令输出最后的提示执行类似命令：
source "/Users/aven/.sdkman/bin/sdkman-init.sh"注意：你在命令输出中到的提示命令可能与我的不完全相同，至少我们的用户名不相同。
执行完成之后，“sdk”命令就可以使用了：
$ sdk
