Questions tagged [gradle-shadow-plugin]

A Gradle plugin for collapsing all dependencies and project code into a single Jar file.

Shadow is a port of the Maven Shade plugin to Gradle. It allows Gradle to create a Jar artifact containing the contents of all dependencies. Existing infrastructure from Shade is kept where possible in order to support configuration as close to the Maven syntax as possible.
