Michael Osipov commented on MASSEMBLY-833:
------------------------------------------

Guys, I will soon merge https://github.com/codehaus-plexus/plexus-archiver/pull/55 which will require Java 7. We can boldly bump to a new major version cleaning up Plexus Archiver. Otherwise I will bump only minor and merge the PR as well as PR #52.

> Motivation: Having extremely large multi-module project, some modules lets call them "application" modules provide "configuration" files, and they provide them for different environments. Problem is that not all "application" modules provide "configuration" files for all environments. In case there are no files available for assembly, the single goal ends up with ERROR:
> Failed to
>  create assembly: Error creating assembly archive <assembly_name>: You must set at least one file.
> Available workaround is to specify a property to by default skip the assembly execution and only if there are files for given environment set this property to not skip the given assembly execution.
> However for large number of environments this solution starts to be messy and hard to maintain.
> Do you think that having assembly Parameter "ignoreNoFiles" that will cause to skip the archive creation for cases there are no files to package seems like reasonable solution?
