Run the command mvn install clean package -DskipTests to generate a single shaded Jar for all sub-modules in examples/target/scala-2.*/zen-examples-*.jar

I'm still not able to compile: I get an OutOfMemory error from Maven. The end of the Maven log file is enclosed below.

Any other hints?

What version of Maven are you using? You can try to add environment variables:
export MAVEN_OPTS="--Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

Maven version 3.3.9 - yes changing MAVEN_OPTS helped me compile the jar files.
However, to run the example, I had to change the parent's pom.xml file again which had disabled installation of jar files:

So after that diff, the final invocations to get something to run is:
MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m" mvn clean install -DskipTests
cd example
mvn scala:run -DmainClass=com.github.cloudml.zen.examples.ml.LambdaMARTRunner
What would now help is if you can provide an example of the options to use LambdaMARTRunner, e.g. using the LETOR or MSLR datasets, or at least what formats are expected, so I know how to transform such standard datasets?
