重點為 Incompatible because this component declares a component, compatible with Java 11 and the consumer needed a component, compatible with Java 8。

應該是 jdk 版本不對。

但是查資料，在 ide 修改 Gradle 的 jdk 為 11、17 都無效。

解決歷程

1. 在 Terminal 使用命令 java -version 可以顯示 jdk 11。但是轉念一想我係統變數 JAVA_HOME 配的 1.8，蠻奇怪的，會不會有什麼衝突。
2. 修改系統變數 JAVA_HOME 為 jdk 11 版本，以及 Path 變數裡的 bin 路徑。
3. 測試正常
4. 應用打包會提示 Android Gradle plugin requires Java 17 to run. You are currently using Java 11.。
5. 這次使用 IDE 的設定，開啟設定搜尋 Terminal，在 Project Setting 裡設定終端的環境變數：Environment variables: JAVA_HOME=E:/Program Files/Android/Android Studio/jbr，這個是 ide 自帶的 17 jdk。
6. 命令執行正常。

done.
