Under directory docs there is a build.xml and a "tmp" subdir like this:
tmp
|-- aaa
`-- newdir
`-- bbb
If you want create a zip file with tmp as the root folder, you should write build.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
If you only want zip all contents under tmp (without root folder tmp), you should modify build.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
