How to find/remove unused dependencies in Gradle

Question

I wanted to find unused dependencies in my project. Is there a feature for this in Gradle, like in Maven?

You can try the com.github.nullstress.dependency-analysis Gradle plugin

Build script snippet for use in all Gradle versions:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath "com.github.nullstress:DependencyAnalysisPlugin:1.0.3"
  }
}

apply plugin: "com.github.nullstress.dependency-analysis"

Build script snippet for new, incubating, plugin mechanism introduced in Gradle 2.1:

plugins {
  id "com.github.nullstress.dependency-analysis" version "1.0.3"
}

Also, there is a thread (Is there a Gradle equivalent of "mvn dependency:analyze"?) in the Gradle forum about this.
