Robert Scholte commented on MDEP-516:
-------------------------------------
When only calling the plugin goal, there are no artifacts bound to the
MavenProject of the reactor; that's done during the package-phase. The solution
would be to exclude all reactor project from artifact resolution. If the goal
already fails before calling the {{execute()}}-method, then
{{requiresDependencyResolution = ResolutionScope.TEST}} should be replaced with
{{requiresDependencyCollection = ResolutionScope.TEST}} which is a new Maven
3.0 option.
> 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
