Bug ID: 59114
Summary: Inconsistency in Copy Task with empty FileSet
depending on "exclude" pattern
Product: Ant
Version: 1.9.6
Hardware: Macintosh
OS: other
Status: NEW
Severity: minor
Priority: P3

Reproduction Ant Build Script
Overview:
When you are copying an empty FileSet to a target location, the target
directory is created if the empty FileSet was accomplished with '<exclude
name="*" />' but not if it was accomplished with '<exclude name="**" />'
Steps to Reproduce:
1) Download the attached build.xml into an empty directory.
2) Run 'ant' in that directory.
Actual Results:
The results of 'find .' in that directory are:
$> find .
.
./ant-out
./ant-out/cpyExStar
./build.xml
./src
./src/empty
Expected Results:
Either one of the following would be fine outputs:
$> find .
.
./build.xml
./src
./src/empty
$> find .
.
./ant-out
./ant-out/cpyExStar
./ant-out/cpyExStars
./build.xml
./src
./src/empty
This bug is only concerned with the fact that the Copy task behaves differently
based on whether the empty FileSet is obtained with '<exclude name="*" />' or
'<exclude name="**" />'
I will admit that I have a slight preference for the first of the two possible
'Expected Results' because if you don't have anything to copy to the
destination, why create the destination directory at all. But, I don't really
care as long as it is a consistent and reliable result.
Build Environment:
OS: Mac OS X 10.11.3 (although I suspect it could be reproduced on many)
Java Versions: 1.8.0_72, 1.7.0_79, 1.6.0_65
ant version: 1.9.6 (also reproduced from current master branch of any git repo)
