How can I easily remove all stale snapshots from my local repo?

Many files in my repo results in poor performance and the time to fetch artifacts is long. I'd like to keep the repo trimmed down to latest snapshot.

I see that dependency:purge-local-repository can clear the local repository but I want to keep latest. I can easily create a script to do this work (and wrap it in a plugin) but don't want to re-invent the wheel if there's already a tool to purge down to latest.

Is there a plugin that can purge my dependencies to latest-snapshot or last X snapshots?

  • Seems that the mojo's `snapshotsOnly` is not good enough, as you would like like to have something like `oldSnapshotsOnly`? – noahlz Sep 24 '12 at 20:09

This is similar to how-do-you-deal-with-maven-3-timestamped-snapshots-efficiently

I added the following and each build's package clears out the old snapshots keeping my local repository trim and ensuring faster builds on windows which has issues with a bulky repo

     <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <version>1.7</version>
        <executions>           
            <execution>             
                <id>remove-old-artifacts</id>             
                <phase>package</phase>             
                <goals>               
                    <goal>remove-project-artifact</goal>             
                </goals>            
                <configuration>  
                    <removeAll>true</removeAll><!-- remove all versions of built artifacts including all versions.  Install phase will regenerate -->             
                </configuration>          
                </execution>         
        </executions>             
    </plugin>

With Peter's solution, all old versions of current artifact (or group of artifacts, if applied in a parent pom) are deleted, including releases and all snapshots.

If any other projects needs a previous release version, will have to be downloaded again from your non-local repository (say Nexus), and once you create a 'package' of this snapshot, will be deleted again.

I've seen another option for this issue: http://maven.apache.org/plugins/maven-dependency-plugin/purge-local-repository-mojo.html

Has the option of defining 'snapshotsOnly', and will remove only snapshots, not previous stable releases.
