Early versions of tar did not support path lengths greater than 100 characters. Modern versions of tar do so, but in incompatible ways. The behaviour of the tar task when it encounters such paths is controlled by the longfile attribute. If the longfile attribute is set to fail, any long paths will cause the tar task to fail. If the longfile attribute is set to truncate, any long paths will be truncated to the 100 character maximum length prior to adding to the archive. If the value of the longfile attribute is set to omit then files containing long paths will be omitted from the archive. Either option ensures that the archive can be untarred by any compliant version of tar.

> Prefixes of long paths (> 100 chars) are ignored when unpacking archives with tar on linux.
> Packing "moreThan100/long/path/to/file.class" with TarGzExporter, is unpacked by linux tar as "long/path/to/file.class". 
> Where "long/path/to/file.class" is just bellow 100 chars.
