A Gradle plugin for creating fat/uber JARs, transforming files, relocating packages, and optimizing applications with R8/ProGuard. The Gradle counterpart to Maven Shade Plugin.

[!NOTE]
Previously this plugin was developed by @johnrengelman and published under the ID com.github.johnrengelman.shadow before maintenance was transferred to the GradleUp organization to ensure future development, see #908.

If you are still using the old plugin ID in your build script, we recommend to switch to the new plugin ID com.gradleup.shadow and update to the latest version to receive all the latest bug fixes and improvements.
