There is always HTTP 404 Error Where I request the maven2 in workbench

I want to try KieScanner for the remote maven repo. So I setup the workbench and create "Project1" as a sample, I also build and deploy it successfully. I can see the jar named "Project1-1.0.0.jar" with GAV "com.myteam:Project1:1.0.0" exist in “Admin” -> "Artifacts".

So I add the repository into my development pom.xml and the jar as dependency, but the jar can't been downloaded by Maven Project.

I also try to open the url: http://192.168.56.101:8080/kie-drools-wb/maven2, but there is always HTTP Status 404 – Not Found happened with description " The origin server did not find a current representation for the target resource or is not willing to disclose that one exists."
The most funny thing is I can open the url: http://192.168.56.101:8080/kie-drools-wb/maven2/com/myteam/Project1/maven-metadata.xml, the content is shown in my webpage as following:
This XML file does not appear to have any style information associated with it. The document tree is shown below.

</versions>
<lastUpdated>20170913142741</lastUpdated>

As remote maven repo of workbench, why not like my private nexus maven that I can open the link even if it 's a folder?

my pom.xml as following:
