今天回到家裡用電腦，Mac 在用 Expo 運行 Android 應用程式時，除了跟 Windows 電腦一樣要指定 package 名稱，還需要指定 JAVA_HOME 路徑。這樣 Expo 才知道要用哪個來源的 JVM 進行 Android 應用程式的編譯。

Configuration on demand is an incubating feature.

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration 'classpath'.

  Required by:
      unspecified:unspecified:unspecified
   > Dependency requires at least JVM runtime version 11. This build uses a Java 8 JVM.

1. 在 terminal 使用 java -version 查看當前的 Java 版本。
2. echo $SHELL 指令查看目前是使用哪一種 shell: Zsh 或是 Bash
3. nano ~/.zshrc 指令開啟 Zsh 設定檔的編輯器，插入下列設定至檔案尾端。

export JAVA_HOME=/Library/Java/JavaVirtualMachines/corretto-17.0.12/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH

JAVA_HOME 要怎麼找呢？
請看 stackoverflow - How to set JAVA_HOME environment variable on Mac OS X 10.9?

4. 依序按下 Ctrl+X、Y、Enter 存檔。
5. source ~/.zshrc 指令讓你可以立即套用變更而不用重新啟動 terminal。
6. 但是，使用 java -version 再一次查看 Java 版本，仍然是較低的版號。
7. 這時我們要用 SDKMAN 來管理這些眾多的 Java 版本。
8. 使用 sdk list java 查看，原來可用版本有那麼多。

9. 使用 sdk install java 17.0.12-amzn 安裝新版本。

> sdk install java 17.0.12-amzn
We periodically need to update the local cache. Please run:

  $ sdk update

Do you want java 17.0.12-amzn to be set as default? (Y/n): Y

Setting java 17.0.12-amzn as default.

10. 安裝完會提示要不要設為預設版本，選擇 Y。

11. 使用 java -version 再一次查看 Java 版本，總算是新版本了。
