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. *Error message - * INFO] Reactor Summary: [INFO] [INFO] Zeppelin ..........................................

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. - Swapnil
