This is how you can publish your custom jar files as Maven artifacts and use them as dependencies in your projects:

Make sure you have an Azure Artifact feed in Azure DevOps or create one if needed:

The command below will generate a Maven artifact. Please upload the pom.xml and jar file to the Azure DevOps Repo if you don’t have one ready:                                                                                                    mvn -B archetype:generate -DarchetypeGroupId=”org.apache.maven.archetypes” -DgroupId=”MyGroup” -DartifactId=”myFirstApp”                                                

From the “Connect to feed” in Azure DevOps, select the Maven, and copy the <repository> information:

 
Paste <repository> information from the last step, into your pom.xml file twice in <repositories> and <distributionManagement> tags

Create a pipeline in Azure DevOps:  
You can also use settings.xml file to authenticate the Azure DevOps Maven feed in your pipeline.                                                                                      
Configure the feed permission in case of access related issues 
Select the Packages from your feed in Azure DevOps, and copy the contents of the <dependency> element:
Paste the <dependency> element content copied in the last step, inside the <dependencies> element of your project pom.xml file.                               
Run “mvn install” from the directory that contains your project pom.xml file.
