[Chore]: Investigate and fix failure to publish snapshots to Sonatype #333

What

Snapshot publishing to Sonatype is failing for the BerryCloud/xapi-java repository. The problem involves the configuration for the snapshot repository (id 'central', URL 'https://central.sonatype.com/repository/maven-snapshots/'), Maven deploy commands, or related plugin/auth changes that are preventing successful upload of SNAPSHOT artifacts.

Why

This chore is necessary to restore snapshot publishing, which is essential for continuous integration, dependency testing, and early access builds. Without snapshot deployments, teams cannot properly test changes, access up-to-date builds, or distribute development versions.

Notes

The issue may be caused by changes to Sonatype snapshot coordinates, authentication requirements, or Maven plugin compatibility. Example steps to reproduce:

1. Run mvn deploy or CI snapshot workflow
2. Observe publishing failure (artifacts remain local, no upload)
   Please investigate necessary updates to configuration, credentials, or documentation to restore publishing.
