Using Maven-3 Got Http 409 Error When Redeploying Using Archiva

I am deploying a jar file to the maven repository (archiva)

pom.xml:

<distributionManagement>
  <repository>      
    <id>archiva.internal</id>
    <uniqueVersion>false</uniqueVersion>
    <name>Internal Release Repository</name>
    <url>http://server:8080/archiva/repository/internal</url>
  </repository>
  <snapshotRepository>
    <id>archiva.snapshots</id>
    <uniqueVersion>false</uniqueVersion>
    <name>Internal Snapshot Repository</name>
    <url>http://server:8080/archiva/repository/internal/snapshots</url>
  </snapshotRepository>
</distributionManagement>

settings.xml:

<servers>
    <server>
        <id>archiva.internal</id>
        <username>user</username>
        <password>password</password>
        <filePermissions>664</filePermissions>
        <directoryPermissions>775</directoryPermissions>
    </server>
    <server>
        <id>archiva.snapshots</id>
        <username>user</username>
        <password>password</password>
        <filePermissions>664</filePermissions>
        <directoryPermissions>775</directoryPermissions>
    </server>

</servers>

The first maven deployment is success,

Uploading: http://server:8080/archiva/repository/internal/com/test/maven-metadata.xml
Uploaded: http://server:8080/archiva/repository/internal/com/test/maven-metadata.xml (306 B at 2.4 KB/sec)

If I try to redo the same artifact, I get:

Failed to transfer file: http://server:8080/archiva/repository/internal/com/test.jar. Return code is: 409 -> [Help 1]

Is it possible to redeploy the same artifact with the same version, or do I need to manually remove the artifact from the archive before redeploying?
