Description

I have one artifact, in the simplest case only with two resources inside:

ResourceArtifact-1.0.jar
/resource1.dat
/resource2.dat

I want to unpack one resource into one location and the second in a different location, all this with one pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.0.2</version>
    <executions>
      <execution>
        <id>unpack-resource1</id>
        <goals>
          <goal>unpack-dependencies</goal>
        </goals>
        <configuration>
          <includeArtifactIds>ResourceArtifact</includeArtifactIds>
          <includes>resource1.dat</includes>
          <outputDirectory>resources1</outputDirectory>                
        </configuration>
      </execution>
      <execution>
        <id>unpack-resource2</id>
        <goals>
          <goal>unpack-dependencies</goal>
        </goals>
        <configuration>
          <includeArtifactIds>ResourceArtifact</includeArtifactIds>
          <includes>resource2.dat</includes>
          <outputDirectory>resources2</outputDirectory>                
        </configuration>
      </execution>
  </executions>
</plugin>

When I don't use (which makes not so much sense, because in fact there's nothing to overwrite):

<overWriteReleases>true</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>

Then I get an info (even not a warning):

[INFO] --- maven-dependency-plugin:3.0.2:unpack-dependencies (unpack-resource2) @ maven-unpack-same-artifact ---
[INFO] test:ResourceArtifact:jar:1.0 already exists in destination.

And the second resource is not unpacked.
