title: Rename shadow jar produced by shadow plugin to original artifact name
body: <p>I am using gradle shadow plugin to build my uber jar.</p>
  
  <p>build.grade file looks like:</p>
  
  <pre><code>buildscript {
      repositories {
          jcenter()
      }
      dependencies {
          classpath 'com.github.jengelman.gradle.plugins:shadow:2.0.2'
      }
  }
  
  apply plugin: 'com.github.johnrengelman.shadow'
  
  
  dependencies {
     compile "com.amazonaws:aws-lambda-java-events:1.3.0"
  
  }
  
  assemble.dependsOn(shadowJar)
  </code></pre>
  
  <p>It produces following jars in build/libs folder.</p>
  
  <pre><code>myProject-1.0.0-SNAPSHOT.jar
  myProject-1.0.0-SNAPSHOT-all.jar '//uber jar
  </code></pre>
  
  <p>I want to replace original jar with uber jar. How do i do this?</p>
