Aaron Kimball updated HADOOP-5240:
----------------------------------
Attachment: patch
Attached patch uses a timestamp file and an <uptodate> task to determine if
javadoc is necessary. "ant package" seems to update a lot of site files,
though, which invalidates this, but in the general case this will speed up
recompilation.
> 'ant javadoc' does not check whether outputs are up to date and always
> rebuilds

> Running 'ant javadoc' twice in a row calls the javadoc program both times; it
> doesn't check to see whether this is redundant work.
