Disable the generation of pom

By default, If no pom is specified during deployment of your 3rd party artifact, a generic pom will be generated which contains the minimum required elements needed for the pom. In order to disable it, set the generatePom parameter to false.

mvn org.apache.maven.plugins:maven-deploy-plugin:3.1.4:deploy-file -Durl=file:///C:/m2-repo \
 -DrepositoryId=some.id \
 -Dfile=path-to-your-artifact-jar \
 -DgroupId=your.groupId \
 -DartifactId=your-artifactId \
 -Dversion=version \
 -Dpackaging=jar \
 -DgeneratePom=false

Note: By using the fully qualified path of a goal, you're ensured to be using the preferred version of the maven-deploy-plugin. When using mvn deploy:deploy-file its version depends on its specification in the pom or the version of Apache Maven.
