Tar and Zip arhivers can't handle >2GB, need to synchronize with Ant's zip and tar source

Attached is the diff with the zip and tar packages copied from

http://svn.apache.org/repos/asf/ant/core/tags/ANT_170/src/main/org/apache/tools/

with package renamed to codehaus.

fixed:

2GB zip limitation, it now works with <4G. Still have limittation of 4GB but better
2GB tar file entry size limittable

Please see Ant's svn log for more details

I tested with 25 Gig tar

Are the licenses actually correct?

That aside:
1) I really don't think that the added distribution management is correct
2) The code has been re-formatted away from the Plexus style, can this be fixed?

my bad,

1. The license is from orignal ant 1.7.0 code

2. Distribution Management is my mistake

3 The code is from Ant 1.7 do you have Plexus style I can apply?

Will make another attemp shortly

-D

if the code comes form Ant, does it really make sense not to use it directly?

If not possible I wouldn't change the package names or formatting so future diffs of both codebases are easier. And consider creating a branch of the ant code at codehaus.

Wouldn't changing the package name be necessary to avoid the potential for weird classpath issues if both ant and plexus were being used in the same project?

Code style is as maven code style

Max: Interesting point with the package names, forked code will likely need a different package name to avoid just that issue.

another attemp, this time:

• copy neccessary files from ant-1.7.0 to plexus-archiver
• change license header the match with other files
• change style to using latest maven format style( still look messy thou due to many changes since last sync)

+1 to add dependency to ant jars and reuse the code

I really think this is an urgent matter that needs to be addressed, we've got a few tar files close to 3GB and this is a very annoying limitation...

An alternative is "truezip". See the truezip-maven-plugin. Seems to be a much better archiver implementation than the ant implementation. Much much faster.

actually behind the scence, truezip uses ant's internal implementation of tar,gzip, and bzip

commons-compress has been released

using commons-compress 1.1 could be an option
