我正在尝试使用将 JDK 17 安装到 macOS BigSur (11.5.2)brew install openjdk@17

> brew install openjdk@17
Running `brew update --preinstall`...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).
==> Updated Formulae
Updated 3 formulae.

openjdk  is already installed but outdated (so it will be upgraded).

==> Caveats
For the system Java wrappers to find this JDK, symlink it with
  sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

openjdk is keg-only, which means it was not symlinked into /usr/local,
because macOS provides similar software and installing this software in
parallel can cause all kinds of trouble.

If you need to have openjdk first in your PATH, run:
  echo 'export PATH="/usr/local/opt/openjdk/bin:$PATH"' >> ~/.zshrc

For compilers to find openjdk you may need to set:
  export CPPFLAGS="-I/usr/local/opt/openjdk/include"

安装后jenv找不到java17的实例

jenv versions

发现需要在 jenv 中注册 java-17 dist 使用命令：

jenv add /usr/local/opt/openjdk/libexec/openjdk.jdk/Contents/Home

您的路径/usr/local/opt/openjdk/libexec/openjdk.jdk可以从您的 brew 安装日志（在线找到sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk ...）中获取，然后添加/Contents/Home

现在，它有效
