Summary: Unpack Incredibly Slow for
Key: MDEP-421
URL: https://jira.codehaus.org/browse/MDEP-421
Project: Maven 2.x Dependency Plugin
Issue Type: Bug
Components: unpack-dependencies
Affects Versions: 2.8
Reporter: Mike Gilbode
I've got a zipfile that is 240MB and has ~84k entries. I'm trying to use
unpack-dependencies and it is taking an inordinate amount of time such that it
is basically unusable. It seems that it's eagerly trying to read through every
zip file entry before actually unpacking. This takes roughly 15 minutes where
using the maven antrun plugin / unzip task takes less than a minute.
