tar command 'U' option not supported on Solaris OS.

Unlike the site plugin that uses a property to set the tar program used (maven.site.tar.executable), the dist plugin uses the hard coded string 'tar' to run the tar command. This is a problem on Solaris OS where the 'U' option is not supported by the standard tar program.

Below is the snippet of plugin.jelly script in question (dist:deploy goal) -

<deploy:artifact
artifact="distributions.tar.gz"
type="distributions"
assureDirectoryCommand="mkdir -p"
siteCommand="cd @deployDirectory@;gunzip distributions.tar.gz;tar xUvf distributions.tar;chmod -R g+u *;rm distributions.tar"
/>

It would seem appropriate/consistent to replace the hard coded string with a 'maven.dist.tar.executable' to allow a different tar program, i.e. GNU tar, that supports the 'U' to be used. This would default to a value of 'tar' and therefore be transparent in behaviour for most people.

This bug was also present in Beta 10.

Cheers,

Martin.
