Apache - Zeppelin build failed on Ubuntu - apache-zeppelin

Question

I am so stuck in this. I have followed each and every single instruction here (https://github.com/apache/incubator-zeppelin)
to install Apache-Zeppelin. I need this for Spark.
Below are various required applications installed in UBUNTU (VM)
hduser#HDPMaster:~$ java -version
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)
hduser#HDPMaster:~$ mvn --version

Cloned Zeppelin from Git Hub
git clone https://github.com/apache/incubator-zeppelin.git
Initially, I had Maven 3.0 version. One of the threads suggested to have a version > 3.3..Installed the latest version (3.3.9).
executed the below command which is still failing
mvn clean package -DskipTests -Pspark-1.5.2 -Phadoop-2.7.1

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR] mvn <goals> -rf :zeppelin-flink
No idea where to go from here. Are there any changes required in any of the settings in zeppelin folder ? Suggestions please.

Answer 1

I don't know the reason behind it but this problem got solved. I just ran the below command in the morning and build was successful
mvn install -DskipTests
Not sure if there is a logic behind that but if someone knows please share that.

Answer 2

If you have cloned zeppelin from git, then you need to go to the 'master' folder(in command line) and then run the following command :
mvn clean package -DskipTests -Pspark-1.5.2 -Phadoop-2.7.1
