title: Maven release plugin - how to publish only a snapshot?
body: <p>I'm using maven release plugin to deploy new versions of software.
  When running</p>
  <pre><code>mvn release:prepare
  mvn release:perform
  </code></pre>
  <p>Everything works as expected.
  If I tell maven to release version 2.1, it publishes an artifact <code>2.1</code> as well as a <code>2.2-20210205.061032-1</code>, which I guess is some kind of snapshot. I'm wondering if it´s possible to perform a release for a new snapshot version ONLY?</p>
  <p>The use case being that I have made some changes I want to publish for testing, before commiting to a final release. Something like <code>2.2-SNAPSHOT</code>, or something like <code>2.2-YYYYMMDD.HHmmSS-X</code>.
  When prompted by maven to enter the next version, if I enter <code>2.2-SNAPSHOT</code>, it just repeats the question again.</p>
  <p>Please advice on how to achieve this, or if I'm thinking about this the wrong way.</p>
