> Hi,
> I'm new to the project and trying to follow the instructions on [https://beam.apache.org/documentation/runners/flink/] for the portable flink runner, but they are out of date. I'd love to see the docs updated so that users like myself can do this successfully.
> The first issue is that all of the source releases that I downloaded, from both github and the downloads page, had the gradlew file removed.  I had to clone the repo to solve this problem.
> The next problem that I encountered was this:
> {code:java}
> chad$ ./gradlew :sdks:python:container:docker
> Configuration on demand is an incubating feature.
> FAILURE: Build failed with an exception.
> * What went wrong:
> Project 'sdks' not found in root project 'beam'.
> {code}
>   
> The proper command is: 
> {code:java}
> ./gradlew :beam-sdks-python-container:docker{code}
>  
> Likewise, the next command should be:
> {code:java}
> ./gradlew :beam-runners-flink-1.7-job-server:runShadow -PflinkMasterUrl=localhost:8081{code}
>   
> After that I was able to get the flink beam example working.  I recommend adding this to the docs:
> {code:java}
> (.venv) chad$ python -m apache_beam.examples.flink.flink_streaming_impulse{code}
>  
> also, since the docs specify only flink 1.7 is compatible with beam 2.12 (the latest as of this writing), I had to do a little extra work to get flink 1.7 built instead of 1.8, but this is probably outside the scope of the beam docs:
> {code:java}
> brew install https://raw.github.com/Homebrew/homebrew-core/97b7a467beb81412bef2fbc497671c8ad3d407e5/Formula/apache-flink.rb
> /usr/local/Cellar/apache-flink/1.7.2/libexec/bin/start-cluster.sh{code}
> thanks!
