why can't i upload artifact to archiva (Unauthorized), but i can download from it with admin user?

I'm working with archiva for about a year now,

I upload my jars manually through archiva GUI,and it's working fine.

Now I want to upload an artifact with maven deploy,the problem is that I get 401-Unauthorized. bare in mind that:

1.) I can download from this repository with no problem .

2.) I use admin user .

3.) I can upload with this user manually.

this is the log that I get:

[com:apinterface.parent] Downloading: http://xx.xx.xx.xx:9080/archiva/repository/snapshots/com/apinterface.parent/1.0-SNAPSHOT/maven-metadata.xml

Solution

This should be because you haven't configured Maven to use the Archiva Username/Password for uploading artifacts during the deploy phase.

I assume you have already configured the distributionManagement section in your pom file.

<distributionManagement>
    <snapshotRepository>
        <id>snapshots</id>
        <name>Internal Snapshots</name>
        <url>http://xx.xx.xx.xx:9080/archiva/repository/snapshots/</url>
    </snapshotRepository>
    <repository>
        <id>releases</id>
        <name>Internal Releases</name>
        <url>http://xx.xx.xx.xx:9080/archiva/repository/releases</url>
    </repository>
</distributionManagement>

You should have servers with matching ids in your Maven Settings file (like in the sample below) to configure the username/password which maven should use while uploading(deploy) the artifacts

<settings>
  <servers>
    <server>
      <id>snapshots</id>
      <username>archiva-user</username>
      <password>archiva-pwd</password>
    </server>
    <server>
      <id>releases</id>
      <username>archiva-user</username>
      <password>archiva-pwd</password>
    </server>
  </servers>
</settings>
