I am getting an error when I use the unzip task to expand a tar file created
using the tar task.
Below is a sample of the code I am executing as well as the error I am
recieving.
Can anyone help with this?
listing of build.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<project name="TarTest" default="unTar" basedir=".">
<property name="tardir" value="${basedir}/tar" />
<property name="buildTemp" value="${basedir}/buildTemp" />
<property name="TestFilesDir" value="${buildTemp}/TestFilesDir" />
<property name="expandedFilesDir" value="${basedir}/expandedFiles" />
<!-- expand the tar file -->
<target name ="unTar" depends="makeTar" >
<unzip src="${tardir}/test.tar" dest="${TARdistributionDir}" />
</target>
<!-- create the tar file -->
<target name ="makeTar" depends="buildTestFiles" >
<mkdir dir="${tardir}"/>
<tar destfile="${tardir}/test.tar" basedir="${buildTemp}" />
</target>
<!-- create some files -->
<target name="buildTestFiles" depends="prepareDirs" >
<concat destfile="${TestFilesDir}/file1.txt">This is file1</concat>
<concat destfile="${TestFilesDir}/file2.txt">This is file2</concat>
<concat destfile="${TestFilesDir}/file3.txt">This is file3</concat>
</target>
<!-- create reqrd dirs -->
<target name="prepareDirs" >
<mkdir dir="${tardir}"/>
<mkdir dir="${buildTemp}"/>
<mkdir dir="${TestFilesDir}"/>
<mkdir dir="${expandedFilesDir}"/>
</target>
</project>
