This skill provides a standardized workflow for publishing Java/Kotlin libraries to the Maven Central Repository using the modern Central Portal (via central-publishing-maven-plugin).

📋 Prerequisites

2. Namespace Verified: You must have verified your groupId (e.g., io.github.username or com.yourdomain) in the portal.
3. User Token: Generated from the Central Portal (My Account -> Generate User Token).

🛠️ Environment Setup

1. Install Tools

Ensure maven, gnupg, and openjdk-17+ are installed.
