Packs a resource using the GZip or BZip2 algorithm. The output file is only generated if it doesn't exist or the source resource is newer.
| Attribute | Description | Required |
| src | the file to gzip/bzip. | Yes, or a nested resource collection. |
| destfile | the destination file to create. | Exactly one of the two. |
| zipfile | the deprecated old name of destfile. |
The specified resource will be used as src. Since Apache Ant 1.7
<gzip src="test.tar" destfile="test.tar.gz"/>
<bzip2 src="test.tar" destfile="test.tar.bz2"/>
<gzip destfile="archive.tar.gz"> <url url="http://example.org/archive.tar"/> </gzip>
downloads http://example.org/archive.tar and compresses it to archive.tar.gz in the project's basedir on the fly.
