[jira] [Commented] (MDEP-516) Go-offline does not find module dependencies in multi-module build.

Dominik Drzewiecki commented on MDEP-516:
-----------------------------------------

This issue is particularly annoying in multistage Docker builds when one wants to cache all depenencies in one of the early image layers in order to avoid excessive artifacts/plugins retrievals during subsequent builds.

> 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
