> The reason of this error output is that the zinc is not supported well on
> aarch64, unfortunately, the stand alone zinc is deprecated now[2], so that we
> have no chance to support it on aarch64 in stand alone verison.
> Looks like we should skip the zinc related command on aarch64 platform first,
> and then upgrade the sbt/zinc[3] in future.
