About

Shadow is an extension of the Gradle Jar task that optimizes FatJar/UberJar creation by using JarInputStream and JarOutputStream to copy file contents. This avoids the unnecessary I/O overhead of expanding jar files to disk before recombining them. Shadow provides the similar filtering, relocation, and transformation capabilities as the Maven Shade plugin.
