Jason Lemay updated MASSEMBLY-709:
----------------------------------

    Description: 
When assembling a zip where duplicate files are copied to the output directory 
the default behavior is for the first file to copy and the remaining ones to be 
skipped. When building a project on windows this is not the behavior. On 
Windows all the duplicate files are added to the final zip assembly.

This was tested on OSX, CentOS, and Windows Server 2009 R2.

Using OSX with these settings:
{code}
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 
05:51:28-0800)
Maven home: /usr/local/Cellar/maven30/3.0.5/libexec
Java version: 1.7.0_60, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9.4", arch: "x86_64", family: "mac"
{code}

Running the mvn build as such:
{code}
mvn -X clean install
{code}

You end up with this logged to the console:
{code}
[INFO] Building zip: /Users/jasonl/Desktop/sample/target/sample.zip
[DEBUG] adding directory sample/
[DEBUG] adding directory sample/conf/
[DEBUG] adding entry sample/conf/ConfFile.txt
[DEBUG] adding entry sample/file.txt
[DEBUG] sample/conf/ConfFile.txt already added, skipping
{code}

When the final zip is examined there are no duplicate files. The plugin worked 
as intended.

The problem arises when you build on windows.

Building with these settings:
{code}
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19

Default locale: en_US, platform encoding: Cp1252
OS name: "windows server 2008 r2", version: "6.1", arch: "amd64", family: 
"windows"
{code}

And running the same mvn command:
{code}
mvn -X clean install
{code}

The following is output to the console:
{code}
[INFO] Building zip: C:\Users\Administrator\Desktop\sample\target\sample.zip
[DEBUG] adding directory sample/
[DEBUG] adding directory sample/conf/
[DEBUG] adding entry sample/conf/ConfFile.txt
[DEBUG] adding entry sample/file.txt
[DEBUG] adding entry sample/conf/ConfFile.txt
{code}

As you can see the assembly did not skip the second ConfFile.txt addition. When 
the final zip assembly is examined there is infact 2 ConfFile.txt files under 
the conf directory.

Attached is the sample I used.
