           Summary: Add method to explicitly define symlinks in <tar> task
           Product: Ant
           Version: 1.6.5
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: kriff@espial.com


Bug #15244 explains why it's pretty hard to read symlinks from the filesystem. 
However, it occurred to me that there's no reason why the <tar> task couldn't 
be told explicitly what symlinks to create and include them in the archive. The 
advantage with this approach is that I could run the build script on Windows 
(which doesn't support symlinks in the Unix sense) and still generate a .tar 
archive that could be extracted on Linux with the proper symlinks.

I'm proposing the creation of a nested <symlink> element that provides the name 
and target (and perhaps other attributes) for the symlink. The <tar> task would 
read the element and generate a symlink within the .tar archive. At no point 
would there need to be a symlink on the actual filesystem itself.

For example, this would create a symlink called "link" (in the root directory) 
with a relative path pointing to the file "foo/bar/target":

<tar destfile="archive.tar">
    <tarfileset dir="somedir">
        <include name="foo/bar/target"/>
    </tarfileset>
    <symlink name="link" target="foo/bar/target"/>
</tar>

Another option might be to have the <symlink> element under the <tarfileset> 
element so that it can inherit settings like user, group and permissions.
