Maven fails to transfer one of many artifacts on same repo

Question

I'm trying to create an archetype from an existing project using mvn archetype:create-from-project but I'm getting

Could not transfer artifact org.apache.maven.archetype:archetype-packaging:pom:3.0.0 
from/to central (https://repo.maven.apache.org/maven2):
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: 
unable to find valid certification path to requested target

I am behind a firewall so I followed this post https://stackoverflow.com/a/25912982/358794 and then executed:

$ mvn archetype:create-from-project -Djavax.net.ssl.keyStore=trustCARoot.jks
 -Djavax.net.ssl.keyStorePassword=password  
 -Djavax.net.ssl.keyStoreType=JKS
 -Djavax.net.ssl.trustStore=trustCARoot.jks  
 -Djavax.net.ssl.trustStorePassword=password  
 -Djavax.net.ssl.trustStoreType=JKS

I still get the same PKIX path build failure but just for archetype-packaging

If I clear a dependency as a test of setting up my trustStore, mv archetype-catalog archetype-catalog_backup and rerun it does connect to the repo and redownloads archetype-catalog but still gets hung up on archetype-packaging

Trying to download just archetype-packaging yields the same error

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=https://repo.maven.apache.org/maven2 \
    -Dartifact=org.apache.maven.archetype:archetype-packaging:3.0.0
    -Djavax.net.ssl.keyStore=trustCARoot.jks -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.keyStoreType=JKS  -Djavax.net.ssl.trustStore=trustCARoot.jks  -Djavax.net.ssl.trustStorePassword=password -Djavax.net.ssl.trustStoreType=JKS

Any ideas on how to get a BUILD SUCCESS? I'm able to right click on each file in the browser and save into the local repository but when I try to execute goal mvn archetype:create-from-project maven still tries to download the archetype-packaging

Answer 1

The answer provided here, adding the new maven repository in my settings.xml finally solved the issue Problems using Maven and SSL behind proxy

Earlier, I kept focusing on trying to generate the cert and including it in my trustStore but that never solved the issue.

I still needed to specify my proxy in the settings.xml as well
