解决:  在具体命令增加-v 参数

flutter run apk -v

得到具体的日志, 部分如下

不要被"WARNING"误导(warning是插件在flutter build出错时输出, 但不是导致出错的根本原因)

定位到"FAILED"行: [ +700 ms] > Task :app:processPkgDebugResources FAILED

这才是build失败的原因: 可能是加载Android资源失败导致

打开Android Studio仔细处理IDE 的错误提示(Error 级别)

总结: 查看build日志中 FAILED 行, 不要被 WARNING 误导, 具体 case 具体处理即可
