How to upload a standalone POM to Azure artifacts?

Question

Previously I have successfully uploaded the POM file to Azure Artifacts using

mvn  org.apache.maven.plugins:maven-deploy-plugin:2.4:deploy-file     
-Dpackaging=jar    
-DrepositoryId=repoID    
-Durl=https://pkgs.dev.azure.com/path    
-DgroupId=groupId    
-DartifactId=artifactId    
-Dversion=version     
-Dfile=artifactId-version.jar
-DpomFile=artifactId-version.pom

This works very well, but the problem is I have to now upload an artifact with only POM and without JAR https://repository.jboss.org/org/jboss/resteasy/resteasy-jaxrs-all/3.0.19.Final/

I tried this but it is failing

mvn  org.apache.maven.plugins:maven-deploy-plugin:2.4:deploy-file    
-Dpackaging=jar       
-DrepositoryId=repoID       
-Durl=https://pkgs.dev.azure.com/path    
-DgroupId=org.jboss.resteasy     
-DartifactId=resteasy-jaxrs-all        
-Dversion=3.0.19.Final     
-DpomFile=resteasy-jaxrs-all-3.0.19.Final.pom    

I am getting the following error

Answer 1

file is a required parameter in Apache Maven Deploy Plugin. See the detailed info from deploy:deploy-file. To publish an artifact with only pom and without jar, you can change the value of packaging to pom and set file to your pom file. For example,

mvn deploy:deploy-file -Dpackaging=pom -DrepositoryId=YourRepoID -DgroupId=YourGroupID -DartifactId=YourArtifactID -Dversion=7.0-SNAPSHOT -DpomFile=pom.xml -Dfile=pom.xml

Checking the package in Azure artifact, only pom is published.
