    copied!<p>We use especially for this purpose the <a href="http://mojo.codehaus.org/build-helper-maven-plugin/remove-project-artifact-mojo.html" rel="nofollow">build-helper plugin</a>. In our company parent pom is the remove-project-artifact goal embedded in the profile for our hudson builds. This way all old versions of this artifact are removed prior to installing the currently build version.</p> <pre><code>... &lt;profile&gt; &lt;id&gt;hudson&lt;/id&gt; &lt;activation&gt; &lt;property&gt; &lt;name&gt;BUILD_TAG&lt;/name&gt; &lt;/property&gt; &lt;/activation&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt; &lt;artifactId&gt;build-helper-maven-plugin&lt;/artifactId&gt; &lt;version&gt;1.7&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;remove-old-artifacts&lt;/id&gt; &lt;phase&gt;package&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;remove-project-artifact&lt;/goal&gt; &lt;/goals&gt; &lt;configuration&gt; &lt;removeAll&gt;true&lt;/removeAll&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; ... </code></pre> <p>Using removeAll set to true will wipe out all other snapshots except the one your working on. This can be dangerous as it may mean snapshots for a branch will be wiped out as well.</p> <p>For instance if you have a snapshot 1.0.0.18-SNAPSHOT representing HEAD and snapshot 1.0.1.17-SNAPSHOT representing a branch, running this plugin with 1.0.0.18-SNAPSHOT build will wipe the 1.0.1.17-SNAPSHOt folder.</p> <p>To get around this scenario the removeAll should be set to false.</p>
