Zeppelin build from source

[Swapnil Shinde <sw...@gmail.com>]

Hello Everyone
     I am new to zeppelin world and trying to build zeppelin source code
for the first time. I am building it in *windows* platform. Below are the
steps I followed to build and difficuties/workaround I faced-

*1. Update pom.xml to use scala 2.11. (Successful)*

./dev/change_scala_version.sh 2.11


*2. Build (Error)*

mvn clean package -DskipTests -Pmapr51 -Pspark-2.0 -Dspark.version=2.0.1
-Phadoop-2.7 -Pscala-2.11 -Pr -Pexamples

    Above command was running until zepplin-web build. zeppelin-web was
stuck at log "*npm clean run*" at "*yarn run build*" for very long time. I
tried to build it using cygwin just in case but no luck.

*Workaround* - Then I followed instructions in readme.md to build it step
by step -


# install required depepdencies and bower packages (only once)
$ npm install -g yarn
$ yarn install

# build zeppelin-web for production
$ yarn run build


Above commands run fine but "mvn clean package" under zeppelin-web is still
hanging.

Therefore, I build zepplin-web with step by step commands and then removed
zeppling web as module from parent pom. If I run "mvn clean package
-DskipTests" on parent pom (entire zeppeling project) it throws error while
building zeppelin-server.

I am not sure how to fix this enforcer plugin issue. It would nice if you
guys let me know if I am building it wrong from the beginning or how to
solve this enforcer error.
Thank you very much and let me know if you need any further information.
