Raghu Angadi resolved HADOOP-2147.
----------------------------------
Resolution: Won't Fix
I thought not removing build dir was more prevalent convention. Any way, using
custom build directory might need some fixes :
{noformat}
> ant
> ls build
ant classes examples hadoop-0.16.0-dev-datajoin.jar
hadoop-0.16.0-dev-streaming.jar test
c++ contrib hadoop-0.16.0-dev-abacus.jar hadoop-0.16.0-dev-hbase.jar src
webapps
------
> ant -Dbuild.dir=buildx
> ls buildx
ant c++ classes examples src test webapp
{noformat}
Both builds were successful.
> 'ant clean' should not remove build directory.

> It would be better if 'ant clean' does not remove build directory. Many
> projects do not remove this dir. One advantage of not removing is that, I can
> symlink the build to another place (e.g. /mnt/scratch/) and keep the source
> code in more reliable place. I will submit a patch if this sounds ok.
