Using Maven-3 Got Http 409 error when re-deploy wi

Question

I am deploying jar file to 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>

First maven deploy 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 redeploy 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 have to manually delete the artifact from archive prior to re-deploy?

Answer 1

As an administrator, go to the repositories page and edit the managed repository internal - there you can uncheck Block Re-deployment of Released Artifacts.

However, I wouldn't recommend it in general. Once something is there, it can be downloaded. Once it is downloaded, it can be cached by Maven. If you change it, you won't know that the "real" release is being used everywhere.

Version numbers are cheap - it's better to use a new one.
