maven dependency:copy across modules - maven-dependency-plugin

Question

Have a project with several module projects and itself having other module projects. I have certain modules generating a special artifact type '.kar', and I am deploying this to artifactory during maven deploy phase.
Now I want to find a way by using this existing pom to download these specific artifacts from artifactory by version.
mvn dependency:copy <> allows me to download this per specific artifact.
I want this to be done via the pom file which generates these artifacts. Problem is when I use the dependency:copy, it only runs on the current pom which may or may not have the special artifact.
If I use it in then it re-deploys all the artifacts and downloads the special artifact correctly. This is not right solution though.

Answer 1

You could add a new module to your project that has <dependencies> to all of your .kar artifacts. In the POM file of this new module you can use the copy-dependencies goal of the maven-dependency-plugin.
<project>
<!-- Integrate this module into your multi-module project. -->
<parent>
<groupId>my.group.id</groupId>
<artifactId>my-parent-pom</artifactId>
<version>1.0.0-SNAPSHOT</version<
</parent>
...
<!-- Add dependencies for all your .kar artifacts. -->
<dependencies>
<dependency>
<groupId>my.group.id</groupId>
<artifactId>kar-artifact-1</artifactId>
<version>${project.version}</version>
<type>kar</type>
</dependency>
<dependency>
<groupId>my.group.id</groupId>
<artifactId>kar-artifact-2</artifactId>
<version>${project.version}</version>
<type>kar</type>
</dependency>
...
</dependencies>
<build>
<plugins>
<!-- Use the maven-dependency-plugin to copy your .kar artifacts. -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
