内存不足编译报错
Killed
ninja: build stopped: subcommand failed.
11:11:40 soong bootstrap failed with: exit status 1
报错原因
内存不足或 OOM
如果看到 Killed 而没有详细错误，几乎可以肯定是 被系统 OOM killer 杀死了。
解决方案-1
增加新的内存条
解决方案-2
- 降低编译线程数量到16
- 扩充交换分区空间
sudo swapoff /swapfile
sudo fallocate -l 64G /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
升级包编译报错信息

报错原因
报错原因：调用 signapk 的 Java 运行时是 Java 8（只支持 class file 52），但 signapk.jar 是用 Java 11（class file 55）编译的
解决方案
- 切换java版本为17：sudo update-alternatives –config java
- 修改脚本中的java版本为17
