if clean is run twice in a row (ie already clean, then run clean) an error is generated.
Integrated in ZooKeeper-trunk #477 (See http://hudson.zones.apache.org/hudson/job/ZooKeeper-trunk/477/)
I just committed this... I ran it with 1.7.0 and it works fine...
533_2 is a new patch - it allows building with 1.7.0 (while still fixing the original problem)
reopening - the "erroronemptydir" only works with ant 1.7.1, I will provide a new patch to get it working with 1.7.0 again.
I just committed this. thanks pat.
Turns out fileset fails if "erroronmissingdir" is not set to false (defaults to true)
I fixed this (added the attr as false) and also cleaned up the code a bit (moved the common build code into the reused build xml file)
double clean works with this.
