Robert Scholte commented on MDEP-516:
-------------------------------------
The {{requiresDependencyCollection =true}} is the first step. This will ensure
that that the pom files for all dependencies are available. Next step would be
to download the actual dependencies, excluding the reactor projects.
The goal should also execute {{resolve-plugins}}, but based on your exception
there's a bug there too. Maybe only the plugins are downloaded, but not their
dependencies?
> Go-offline does not find module dependencies in multi-module build.

> Hello,
> I've recently hit the exact same problem that these guys are having:
> http://stackoverflow.com/questions/14694139/how-to-resolve-dependencies-between-modules-within-multi-module-project
> and I thought it must be a very normal scenario so probably a lot of other
> people are hitting.
> So basically I have a multi-module build where {{moduleA}} is built first and
> them {{moduleB}} depends on {{moduleA}}. However when I do {{mvn
> dependency:go-offline}} it comes to resolve the dependencies of {{moduleB}}
> and it fails with {{Artifact not found: moduleA}}.
> That seems to happen because only modules that have been packaged are put in
> the reactor and so later modules will know about them. So to fix it I have to
> do the following:
> {code}
> mvn package dependency:go-offline -U -Pquick,test -DskipTests -s
> src/main/resources/settings.xml
> {code}
> which I really don't like, because it does an extra package that I don't
> need, and then the whole build gets a lot slower.
> of course, {{mvn install}} at any time fixes the issue also, but I don't want
> to install
