编译Pixel Experience 13时遇classcommon解析失败错误求助

我正尝试为Moto G6设备编译Pixel Experience 13，该设备暂无Android 13设备树。作为ROM编译领域的新手，遇到如下编译错误：

解决方案 #

• 定位修复语法错误：打开报错的plat_policy_for_vendor.cil文件第489行，检查是否存在拼写错误（比如classcommon大概率是class common的笔误，缺少空格），或者引用了Android 13中已移除/重命名的SEPolicy类。
• 适配Android 13规则：由于是从旧版本设备树适配，需对照AOSP Android 13的SEPolicy规范，替换过时的规则声明，确保权限、类型定义符合新版本要求。
• 参考同芯片组设备配置：Moto G6搭载骁龙630，找已适配Android 13的同芯片组机型的SEPolicy配置，借鉴其规则修正自己的设备树内容。
• 清理编译缓存：执行make clean或rm -rf out/命令清除旧编译产物，重新初始化编译环境后再尝试编译，避免缓存文件干扰。
