<delete dir="${output}" if="${directory::exists(output)}"/>
default behaviour is true for failonerror, delete should fail if
directory is use.
Here's small a nant function when you want to selectively work with files
which may be in use...in my case I wanted to zip old log files and then
delete them, but not log files in use (i.e. the current projects log files or
any other nant projects running concurrently):
[Function("can-delete-file")]
public bool canDeleteFile(string filename)
{
try
{
StreamWriter w = File.AppendText(filename);
w.Close();
}
catch
{
return false;
}
return true;
}
There is no doubt a more elegant way, but this works.
peace
