[tycho-user] How to set executable bit (chmod 755) on non-root files?

[David M Williams <david_williams@xxxxxxxxxx>]

I'm wondering if anyone has experience
in solving the subject problem? 

On some platforms (hpux) we have an
'so' file that needs be be set executable. Its actually a "launcher
companion" so needs to be set before Eclipse will start (i.e. can
not be set in "metadata", but needs to be set as part of the
zipped up product. 

And ... it is in a plugin (a dir plugin,
not jarred) ... it is not a "root file",  like the eclipse
executable itself. 

See bug 407433 [1] if interested. 

At first, I hoped/assumed if it set
executable "early on" (e.g. in the bundle's POM, with an ant
task) that it would stay executable through out ... but ... permissions
are not maintained. (Is that a bug? Or worth a feature request? -- I know
it would not be "cross-platform", but ... we always build on
Linux). 

I've tried "faking it" as
a root file, and using things like 
root.hpux.gtk.ia64.permissions.755=eclipse,**/*.so
But that had no effect. (Well, the eclipse
executable is set correctly, but not the so file). 
And, BTW, we are using 0.18.0.SNAPSHOT,
so should have wild card support implemented, according to bug 361204 [2].

So, now I am at the point of looking
at the end of the process, right before packaging up the files. We are
using 
tycho-p2-director-plugin
to "materialize-products"
and "archive-products".

It appears the "maven assembler"
has some flexible support for 
<fileMode> but I've not seen anything
like that in Tycho tasks. Am I missing it? 

Honestly, at this point, I'd be happy
to use maven-antrun-plugin to call chmod right before packaging, but I'm
too much a novice to know 
how to get that to execute at the right
point in time (after "on disk", but before zipping up). Is there
a special "phase" I could associate it with? 

Next week, I'll be down to fixing it
post-build, in bash scripts, so any advice on a more "maven like"
solution is most welcome. 

Thanks,
