maven-metadata.xml not generated in artifactory with jenkins

[Yiyito]

Hello guys, IÂŽm not sure how does POM in maven works correctly. Here is the
thing. I was able to create a job with Jenkins Which build & publish a WAR
from java code, to Artifactory using maven (with artifactory plug in) with
job number at the end to keep versioning .Then a maven-metadata.xml is
created on artifactory as showed in first pic (check attach)


After that, on a second job for deploy, with build with parameters option,
I choose artifact selected and deploy the number of war I want like this
(check second image arti2).



Now I wanted to do the same but using maven to ZIP just a folder and
publish to artifactory. I was able to do that with maven assembly plug in
successfully using a POM and a zip.xml file. Thing is that the metadata.xml
in artifactory is not generated like the job with a WAR file I mention at
the beginning. It only generates the zip file (also a jar) but not
metadata.xml which is needed so I can use jenkins to choose Zip file. here
is image from artifactory of Zip generated and error I receive from jenkins
(check third image)



So question is, how does POM generates this metadata.xml file in
artifactory? I used same pom of Java project that was used to build and
publish WAR, except that on last part part I included in <plugin> section
"maven assembly plugin" to zip file. In fact , Zip was successfully
uploaded and created as I showed on image . Here is POM and zip.xml but
metadata.xml not. Anybody knows what can be the issue? thanks!
