Error on excuting the following command: mvn clean install -DskipTests

[krishna murali]

I am trying to setup source code development environment for drools. I am following the step given in the https://github.com/kiegroup/droolsjbpm-build-bootstrap/blob/master/README.md.
First step :

git clone g...@github.com:kiegroup/guvnor.git

This manually i downloaded the guvnor.git file. And extracted it and followed the second step. 
cd guvnor-master;  
mvn clean install -DskipTests

Once i execute the following command i am getting the following error. I am not able to proceed please help me to resolve the error. I am attaching my pom.xml file also.

Above error i have got because proxy is blocking in connecting to maven server. So people behind proxy want to use maven repositories make sure your proxy is set accordingly.
Please refer to the below link for setting the proxy for maven.

I have done the following things.

$git clone https://github.com/kiegroup/drools.git

$cd drools

$mvn clean install -DskipTests

Are the above steps correct to pull drools? or Any thing more i need to do?

[krishna murali]

Thank you all. At last build is success.

I have changed the jdk to openjdk-8 and set the max heap to 4GB even though it is not required that much.

After that i run the maven build. It is success.

Is there a problem with oraclejdk and openjdk?
