- 移除 update-alternatives（对 SDKMAN! 无效） - 纯 JAVA_HOME 方案：安装 JDK 17 到 /usr/lib/jvm，设置 JAVA_HOME - 构建前用 /bin/java -version 硬性验证 - Gradle 通过 -Dorg.gradle.java.home 强制使用 JDK 17 - PATH 首位放 /bin 确保 gradlew 找到正确 JDK

# build.codespace.sh — 在 GitHub Codespaces 中构建 AirDisplay APK
|
||
#
|
||
# 用法:
|
||
# chmod +x build.codespace.sh && ./build.codespace.sh
|
||
#
|
||
# 原理:
|
||
# GitHub Codespaces 通过 SDKMAN! 管理默认 JDK（当前为 JDK 25）。
|
||
# Android Gradle Plugin 8.2.2 不支持 JDK > 21，因此需要 JDK 17。
|
||
# 脚本不做 update-alternatives（对 SDKMAN! 无效），而是直接安装 JDK 17、
|
||
# 设置 JAVA_HOME 指向它，并通过 -Dorg.gradle.java.home= 强递给 Gradle。
|
||
#
|
||
# 环境变量（可选）:
|
||
# ANDROID_SDK_ROOT — SDK 安装路径，默认 $HOME/android-sdk
|
||
# BUILD_TYPE — debug 或 release，默认 debug
