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:2.8.1: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.
