√ Getting environment information

TIP: To avoid setting up the necessary environment variables, you can use the chocolatey package manager to install the Android SDK and its dependencies.

There seem to be issues with your configuration.

√ Component nativescript has 8.4.0 version and is up to date.
√ Your ANDROID_HOME environment variable is set and points to correct directory.

√ The Android SDK is installed.
√ A compatible Android SDK for compilation is found.
√ Local builds for iOS can be executed only on a macOS system. To build for iOS on a different operating system, you can use the NativeScript cloud infrastructure.

是不是多個jdk導致了這個問題，請指導我

提前致謝：）

我嘗試查看命令行錯誤中標記為紅色的文檔以及谷歌上的文檔，但它無處談論多版本問題

Answer 1

1. 請刪除 JDK。

2. 運行 OpenJDK11U-jdk_x64_windows_hotspot_11.0.17_8.msi 再次安裝 JDK。

3. 彈出設置向導Window，點擊Next

4. 然后自定義設置，

(4-1) 在Set JAVA_HOME variable中，下拉選項，select Entire feature will be installed on local hard drive ，(4-2) 在JavaSoft(Oracle) registry keys中，下拉選項，select Entire feature will be installed on local hard drive ，

5. 然后點擊Next ，點擊Install ....

重點是步驟4-2，Register JavaSoft(Oracle) registry keys ，部分windows應用程序會檢查JavaSoft(Oracle)注冊表項，部分Windows應用程序會檢查是否存在JavaSoft Oracle Registry Keys作為判斷系統是否有JDK的依據安裝。

這與是否設置了JAVA_HOME 或PATH 無關。 這些程序用於檢查 JavaSoft Oracle 注冊表項是否存在。

就像 launch4j 將檢查 JavaSoft Oracle 注冊表項。

步驟4-2是假設Eclipse Adoptium JDK是JavaSoft Oracle JDK。
