Ant task to unzip files to a dynamic folder

[Varman]

Hi all,

I too have same requirements in which i want extract zip files to different folders without using custom codes. This is the code am using. this extracts all zip files to "destination_dir" and so files with same name gets overwitten (i want to avoid this). For me each zip file has to be extracted to different folder inside "destination_dir".

           <unzip dest="destination_dir">
                        <fileset dir="source_dir">
                                <include name="**/*.zip"/>
                        </fileset>
            </unzip>

Can you please give me the solution if you have? I saw a thread already posted for this requirement but that was not answered.

Have you tried the ant-contrib for or foreach tasks?
http://ant-contrib.sourceforge.net/tasks/tasks/index.html
Something like

<for param="file">
  <path>
                        <fileset dir="source_dir">
                                <include name="**/*.zip"/>
                        </fileset>
  </path>
  <sequential>
    <propertyregex override="yes"
      property="zipname"  input="@{file}"
      regexp=".*/([^/]*)\.zip" replace="\1"/>
    <mkdir dir="destination_dir/${zipname}"/>
           <unzip dest="destination_dir/${zipname}" src="@{file}"/>
  </sequential>
</for>

perhaps?

Hi,

Great thanks..that works.
But its not working in windows. For windows we have to give something like

      <propertyregex override="yes"
      property="zipname"  input="@{file}"
      regexp=".*\\([^\\]*)\.zip" replace="\1"/>

See the change in regexp. How can i make it generic for both linux and windows?

regexp=".*[\\/]([^\\/]*)\.zip"
perhaps?  Won't work on linux if you actually have a backslash in a
filename, but how likely is that really?
Or you could use the pathconvert task first to force it into one
particular form so you know which to use.  Or use the condition task
with os nested elements to conditionally set some property with the
appropriate regex and use that regexp="${platform.specific.regex}"
The possibilities are endless...
