Fix CodeIris plugin in Android Studio

TL;DR: For the combination of AS 1.2beta and CodeIris 1.13 beta, go to your .AndroidStudioPreview12/config/plugins/CodeIris-Idea/lib and remove your groovy-all jar file.

I wanted to get an UML representation of my classes and one plugin I found was CodeIris. Unfortunately, when I tired to install it, I could not get my project to reload. Bummer. Here are the steps I did to fix it:

1. Close AS
2. Go to .AndroidStudio/system/log and clean it up. Is nicer
3. Open AS
4. Open the log file in your .AndroidStudio/system/log directory
5. Go towards the end and identify the cause of the error. It'll be a java exception
6. Go towards the end of the exception, namely the last Caused by: statement
7. Fix that :)

In my case, the last statements were:

$ run-my-android-app
Caused by: groovy.lang.GroovyRuntimeException: Conflicting module versions. Module [groovy-all is loaded in version 2.2.1 and you are trying to load version 2.3.9

...meaning that CodeIris wanted to load its own groovy library, which differed from the already loaded one.

The fixing process is then simple: remove the groovy library from CodeIris. To do that, go to the location where CodeIris plugin is installed (.AndroidStudioPreview12/config/plugins/CodeIris-Idea/lib in my case) in my case and just remove the groovy jar. then (re)launch AS.

HTH,
