Publishing a Kotlin Multiplatform library sounds simple until you hit Gradle's publishing configuration , signing keys, Sonatype account setup, and POM metadata that silently reject your release with cryptic errors. In this lightning talk, I'll walk through the three specific mistakes that cost me the most time while taking a KMP library from local code to a real, installable Maven Central dependency and exactly what I'd do differently. A practical, no-fluff account for anyone about to publish an Android/Kotlin library.

Key Takeaways:
-The exact Gradle maven-publish + signing configuration that works for KMP (not just single-platform Kotlin)
-How to set up a Sonatype/Maven Central account and namespace correctly
- The most common POM-metadata mistake that causes silent publish rejections, and how to catch it early
-A realistic timeline for going from "library works locally" to "published and installable"
