[jira] [Commented] (MDEP-586) Unpacking different resources into different location from the same artifact doesn't work

["Vidar Breivik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MDEP-586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16729128#comment-16729128 ] 

Vidar Breivik commented on MDEP-586:
------------------------------------

I have looked at this issue and reproduced the behaviour. 
I am a bit uncertain about how this should be solved.

Should the log message be changed from INFO to WARN, and add a helpful text along the line of "...something-something already exists/processed/?, please set <overWriteReleases> or <overWriteSnapshots> to ...something-something"?

Or should the second execution not skip? This looks kind of hard to achieve, because then the second execution will need to know which files were extracted in the first step. My understanding is that now it only looks at a marker-file in target/dependency-maven-plugin-markers, and when it exists it skips (unless overWrite is set).

> 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:
> {code:xml}
> <plugin>

>     <artifactId>maven-dependency-plugin</artifactId>

> </plugin>
> {code}
> When I +*don't*+ use (which makes not so much sense, because in fact there's nothing to overwrite):
> {code:xml}
> <overWriteReleases>true</overWriteReleases>
> <overWriteSnapshots>true</overWriteSnapshots>
> {code}
> Then I get an info (even not a warning):
> {noformat}
> [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.
> {noformat}
> And the second resource is not unpacked.
