• If it’s a feature request, what is your use case :

The use case I have is I’d like to copy the test results in my target directory in the post-integration-test phase from within the running container to the host.

Would be great if we could do something like this -

                 <executions>
                    <execution>
                        <id>copy</id>
                        <phase>post-integration-test</phase>
                        <configuration>
                            <fromContainerDirectory>./target/results/</fromContainerDirectory>
                            <toHostDirectory>./target/results</toHostDirectory>
                        </configuration>
                        <goals>
                            <goal>cp</goal>
                        </goals>
                    </execution>
                </executions>

I suggest to look at mabrarov/redis-builder for those who wants to try copy goal implemented in pull request #1405. mabrarov/redis-builder contains travis/settings.xml Maven configuration file which points to Bintray repository where d-m-p built from the pull request #1405 can be found:
