Hi Rico, you should be able to get it with these steps: git clone https://github.com/StephanEwen/incubator-flink.git flink cd flink git checkout -t origin/windows
This will get you on Stephan's windowing branch. Then you can do a mvn clean install -DskipTests to build it. I will merge his stuff later today, then you should also be able to use it by running the 0.10-SNAPSHOT version.
