Christopher Tubbs commented on MASSEMBLY-941:
---------------------------------------------
One git-specific solution might be to detect that the plugin is running on
files contained within a git repository, and instead of using the
filesystem-detected permissions, just ignore those and use the git-metadata for
the file, {{git ls-files -s path/to/file | cut -c 3-6}}. Or still detect the
executable flag from the filesystem, but preserving it precisely, simplify it
to either 644 or 755, knowing that's all the granularity that git could have
preserved.
> file permissions removed during assembly:single since 3.2.0

> Key: MASSEMBLY-941
> URL: https://issues.apache.org/jira/browse/MASSEMBLY-941
> Project: Maven Assembly Plugin
> Issue Type: Bug
> Components: permissions
> Affects Versions: 3.2.0, 3.3.0
> Reporter: Christopher Tubbs
> Assignee: Herve Boutemy
> Priority: Critical
> Fix For: next-release
>
>
> Since MASSEMBLY-921 in 3.2.0, existing file permissions seem to be ignored
> when creating a tarball assembly, and files stored in the assembly do not
> have their original file permissions preserved.
> Using version 3.1.1 of this plugin and earlier, when creating a tar.gz,
> existing file permissions are normally preserved. This is now broken in
> 3.2.0, unless the component descriptor explicitly sets the fileModes.
> This was discovered trying to prepare a release candidate for Apache Accumulo
> using the apache-23.pom parent POM's predefined `source-release-tar`
> descriptor using the `single` goal. We noticed that the resulting
> source-release tarball had stripped all the executable permissions from our
> scripts, instead of preserving them. This makes the resulting source release
> more difficult to build from source.
> A source-release assembly, and any other assembly that does not specify the
> file permissions explicitly, should preserve the existing file permissions,
> just as it used to with 3.1.1 and earlier.
