Subject [jira] [Commented] (MDEP-572) Truncated filenames extracting tar files.
Date Thu, 22 Jun 2017 18:42:01 GMT


Tim Gokcen commented on MDEP-572:

After some further experimentation, I can confirm that the tar behaviour is still broken in
2.9 but is fixed in release 2.10. I'm guessing it may have had to do with the plexus-archiver
upgrade that was included with that release?

>                 URL:
>             Project: Maven Dependency Plugin
>          Issue Type: Bug
>          Components: unpack
>    Affects Versions: 2.8, 2.9
>            Reporter: Tim Gokcen
>             Fix For: 2.10
> The {{unpack}} goal doesn't handle POSIX.1-2001 long filenames in tar files, silently
truncating file paths to 100 characters. Tarballs that work just fine with BSD or GNU tar
has its filenames truncated by the unpack step (without any kind of warning or error).
> In my particular example, the Tarball was created by the Apache Maven Assembly Plugin
using {{<tarLongFileMode>posix</tarLongFileMode>}}.
> As a work-around, I'm using the org.codehaus.mojo Exec-Maven-Plugin in order to manually
execute tar.
> (Aside: another suggested solution, e.g., on [this StackOverflow question about the issue|]
is to use the Antrun plugin and execute the {{<untar>}} task, but the annoying thing
about that is that Ant doesn't respect file permissions when extracting tar archives)
