3432424
43545435
756767
345354345

You can use loadfile ant task to load the file and HeadFilter in filterchain to filter out only the first line of loaded text.

If your text file e.g. test.txt contains the following

abc
def
ghi

then the the target given bellow will print only the first line abc on the console

<target name="read">
    <loadfile property="temp" srcfile="./test.txt">
        <filterchain>
            <filterreader classname="org.apache.tools.ant.filters.HeadFilter">
                <param name="lines" value="1" />
            </filterreader>
        </filterchain>
    </loadfile>
    <echo>${temp}</echo>
</target>
