Untar / Unzip * .tar.xz with ANT

I want to extract a tarball file with * .tar.xz with ant.

But I can find, bunzip2, gunzip, unzip and untar as targets in ant and none of them work.

So how can I expand a tarball file with * .tar.xz using ant?

XZ format is not supported by default Ant distribution, you will need Apache Compress Antlib .

Download the complete Antlib with all dependencies from here (add three cans ant-compress

, common-compress

, xz

in lib

your ant) and use this task:



<target name="unxz">
    <cmp:unxz src="foo.tar.xz" xmlns:cmp="antlib:org.apache.ant.compress"/>
    <untar src="foo.tar" dest="."/>
    <delete file="foo.tar"/>
</target>

You must use this two-step process because even with the optional Ant library, the value "xz"

is still not supported by the compression

task attribute untar

, the task you would normally use to extract compressed resins.

If someone else like me wants to do the same with maven ant management.
