             Summary: [PATCH] Option to ignore empty directories on fileSet 
directory
                 Key: MASSEMBLY-752
                 URL: https://jira.codehaus.org/browse/MASSEMBLY-752
             Project: Maven Assembly Plugin
          Issue Type: Improvement
    Affects Versions: 2.5.3
            Reporter: Guillaume Boué
         Attachments: MASSEMBLY-ignoreEmptyDirectories.patch

When the directory attribute of fileSets contains empty directories, it would 
be nice to have an option to ignore them.

======= Actual behaviour :

Considering the structure :
src/
   +-- folder1/
      +-- file.txt
   +-- folder2/

with the following fileSet in assembly.xml :
<fileSet>
    <directory>src</directory>
    <outputDirectory>/</outputDirectory>
</fileSet>

the assembly-plugin produces, as of today :
/folder1/file.txt
/folder2

Note that the empty directory folder2 is present in the assembly.

======= Proposed enhancement

With this enhancement, it would be possible to have the following in 
assembly.xml :
<fileSet>
    <directory>src</directory>
    <outputDirectory>/</outputDirectory>
    <includeEmptyDirectories>false</includeEmptyDirectories>
</fileSet>

and the resulting assembly would be :
/folder1/file.txt

Note that folder2 would not be present inside the assembly.

Attached is a patch adding the attribute "includeEmptyDirectories" to fileSet 
element in assembly.xml file. For backward compatibility, the default value of 
this attribute is true.
