[FIXED] Can't prevent Maven deploy plugin from publishing artefact to nexus without version timestamp suffix

Issue

I want to publish my project's artefact .jar to my nexus repository. However the maven deploy plugin always includes a timestamp suffix to the deployed artefact. I followed the documentation to omit the suffix but nothing works - it's still adding it.

The documentation states that <uniqueVersion></uniqueVersion> should be set to false which I did in the pom.xml for every repository configuration and I also used it as a flag like so mvn deploy -DuniqueVersion=false. However nothing works.

The result in Nexus always has the mentioned suffix

Here is my pom.xml:

</project>

Any idea what I am missing or misunderstanding here?

Solution

Support for <uniqueVersion></uniqueVersion> was deprecated in Maven 2.x, and removed entirely in Maven 3. So this is not expected to work, unless you are using the EOL Maven 2. See “major version upgrade to version 3.0” here:
