---------------------------------
Summary: Add `ignoreIfNotExists` to dependency:unpack
Key: MDEP-426
URL: https://jira.codehaus.org/browse/MDEP-426
Project: Maven 2.x Dependency Plugin
Issue Type: New Feature
Components: unpack
Affects Versions: 2.8
Reporter: Ondrej Zizka
The {{dependency:unpack}} goal is often used to manage various files like
(test) resources throughout a multimodule project.
For example, to create a working directory, several artifacts may be unpacked
into a {{workdir/}}.
To configure this it is convenient to set up the goal in the root module.
This works fine, except two things:
1) The root module itself would fail (as the deps don't exist yet)
2) The modules with the resources depend on themselves, i.e. creating a cyclic
dependency.
It would be very convenient if this was handled somehow.
My suggestion to add `ignoreIfNotExists` flag, which would just write an INFO
log message and continue in case that the dependency doesn't exist yet.
That way, users wouldn't have to explicitely enable the execution of the
{{unpack}} goal for every single direct submodule.
Thanks for considering.
