Description

Sanity in CI currently fails with the following error:

A problem occurred evaluating project ':server'.
> Could not resolve all files for configuration ':server:runtimeClasspath'.
   > Could not find org.pytorch:torchserve-plugins-sdk:0.0.4.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/org/pytorch/torchserve-plugins-sdk/0.0.4/torchserve-plugins-sdk-0.0.4.pom
       - https://jcenter.bintray.com/org/pytorch/torchserve-plugins-sdk/0.0.4/torchserve-plugins-sdk-0.0.4.pom
     Required by:
         project :server

The torchserve-plugins-sdk artifacts are currently unavailable via JCenter or Maven Central repositories.

The fix (Reference: https://central.sonatype.org/publish/publish-maven):

• Update the distributionManagement definition in torchserve-plugins-sdk pom.xml to point to Sonatype OSSRH repo.
• Update the torchserve-plugins-sdk version used as dependencies since the current version being built is 0.0.5
• Add nexus-staging-maven-plugin to pom.xml
• Configure maven settings on the host used to deploy to nexus OSSRH

<settings>
  <servers>
    <server>
      <id>ossrh</id>
      <username>your-ossrh-user-id</username>
      <password>your-ossrh-pwd</password>
    </server>
  </servers>
  <profiles>
    <profile>
      <id>ossrh_deploy</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <properties>
        <skip.gpg>false</skip.gpg>
        <gpg.keyname>your-gpg-keyname</gpg.keyname>
        <gpg.passphrase>your-gpg-passphrase</gpg.passphrase>
      </properties>
    </profile>
  </profiles>
</settings>
