Android Module Annotation processor not found

I am trying to package an Android module that I downloaded from Github here:

https://github.com/PDF417/pdf417-titanium

I fixed all the class paths in the build.properties file to fit my system but I get this error:

python.set.exec:

python.check: [echo] Testing for Python [exec] Python 2.7.6

init:

[javac] Compiling 2 source files to (path to the module's android/build/classes folder) [javac] error: Annotation processor 'org.appcelerator.kroll.annotations.generator.KrollJSONGenerator' not found [javac] 1 error

I am running Titanium 3.5.0.GA on Mac OSX 10.10.2. Has anyone else come across this issue or know any fixes for it? It would be much appreciated. Thanks!
