 A [Gradle](http://www.gradle.org) Plugin to create a Mac OSX .app application and dmg based on the project.
 
-**Version 2.1.6 released 4 April 2016.**
+**Version 2.1.7 released 21 July 2017.**
 
 Now available via the Gradle Plugin Portal. Please see:
 http://plugins.gradle.org/plugin/edu.sc.seis.macAppBundle
 
 To add to a gradle project, add this to build.gradle and run **gradle createApp** or **gradle createDmg**. The first should work on most systems, the second will only work on Mac OSX as it uses hdiutils which is a Mac-only application. Also see the [Wiki](https://github.com/crotwell/gradle-macappbundle/wiki/Intro) for more information.
 
-As of version 1.0.9, the 
-groupId and artifactId changed to edu.sc.seis.gradle and macappbundle.
-
 For gradle 2.1 or later:
 ```
 plugins {
-  id "edu.sc.seis.macAppBundle" version "2.1.6"
+  id "edu.sc.seis.macAppBundle" version "2.1.7"
 }
 ```
 
-or for earlier versions of Gradle (which may no longer work, but... ):
-
-```
-
-apply plugin: 'edu.sc.seis.macAppBundle'
-
-macAppBundle {
-    mainClassName = "com.example.myApp.Start"

-
-buildscript {
