The TimestampSelector task takes either a nested element, or a path reference, and sets either a named property, or a `path` instance to absolute pathnames of the files with either the N latest or earliest modification dates (based on the `age` attribute)

Parameters

Attribute Description Required
property The property to set with the most recently modified file. Mutually exclusive with the outputsetid attribute. Yes, if outputsetid is not specified.
outputsetid The id of a path instance which will contain the resulting list of files. This id should not already exist. Mutually exclusive with the property attribute Yes, if property is note specified.
count The number of files to find. If more than 1, than the files in the output appear in the order indicated by the age attribute. No. Defaults to 1
age The age of the files to retrieve, either eldest or youngest. Defaults to youngest. No. Defaults to 1
pathSep The path separator to separate paths with when using the property attribute in conjunction with the count attribute No. Defaults to ,
pathref Id of the path to find the most recently modified file in. No, if a path subelement is specified.

Parameters specified as nested elements

path

Path is used to select sets of files or directories in which to find the most recently modified file

Example

Using a path reference

<path id="mypath">
  <fileset dir="${log.dir}">
    <include name="update*.log" />
  </fileset>
<path>
<timestampselector property="most.recent.logs"
                  pathref="mypath" count="3"
                  pathsep=";" />

<echo message="${most.recent.logs}" />

Using a nested path element

<timestampselector property="most.recent.logs"
                   count="3"
                   pathsep=";" >
  <path>
    <fileset dir="${log.dir}">
      <include name="update*.log" />
    </fileset>
  <path>
</timestampselector>

<echo message="${most.recent.logs}" />

Outputing to a path element

<timestampselector outputsetref="most.recent.logs"
                    pathref="mypath" count="3">
  <path>
    <fileset dir="${log.dir}">
      <include name="update*.log" />
    </fileset>
  <path>
</timestampselector>

<copy todir="somedir">
  <path refid="most.recent.logs" />
</copy>
