[m2] problem w/ dependency-maven-plugin:unpack-dependencies

[Adrian Herscu <bm...@fastmail.fm>]

Hi all,

I have a project with two war modules (app1, app2) that depend one on
the other. I have defined a parent pom.xml (root) in order to be able to
build both project modules at once.

In one of the war modules (app2) I am using the dependency-maven-plugin
in order to merge the artifact produced by the other war module (app1)
into a deployable artifact.

When I am building app2 directly everything works as expected (the app1
artifact is expanded in the webappDirectory).

A weird thing happens when I am building root: the
dependency-maven-plugin does not expand the dependencies.

Adrian.

The pom.xml files are:

1) The root:
