Context: This adds an explicit dependsOn on androidSourcesJar from generateMetadataFileForReleasePublication, which tells Gradle to always run androidSourcesJar first. It's placed inside afterEvaluate so the task is guaranteed to exist when the dependency is declared.

Context: Removed the artifacts { archives androidSourcesJar } block. The sources jar is still explicitly included in the publication via artifact androidSourcesJar, so nothing is lost — it just won't be registered twice, which was causing the duplicate artifact conflict during signing.
