--------------------------------------
@Harsh: You can also do this:
% ant clean package -Divy.checkmodified=false
> Speed up ant builds with the ant uptodate task

> Key: HIVE-3449
> URL: https://issues.apache.org/jira/browse/HIVE-3449
> Project: Hive
> Issue Type: Improvement
> Components: Build Infrastructure
> Affects Versions: 0.9.0
> Reporter: Swarnim Kulkarni
>
> Given that the hive build is an enormously loooong build (~ 6hrs), it might
> be very helpful if there are some checkpointing capabilities available to be
> able to resume a build from failed point and not have to restart everything
> on a single test failure.
> One possible way to do this would be to use the ant uptodate task to check
> set of target files to be more up-to-date than given set of source files and
> execute a target only if that is true.
> By default this capability could be off but can be activated with the
> -Dresume=true argument.
