Adding more memory to h2o.ai Steam Prediction Service Builder - h2o

Question

I trying to build a .war file in h2o steam's prediction service builder using a (~800MB) pojo file (a similara pojo of size ~200MB also produced these same problems). However, when trying this, an error appears after clicking 'build':
Problem accessing /makewar. Reason:
Compilation of pojo failed exit value 3 warning: [options] bootstrap class path not set in conjunction with -source 1.6
The system is out of resources.
Consult the following stack trace for details.

I am launching the Prediction Service Builder from the command line following the instruction in this documentation. Is there a way to launch the service builder with more memory?
UPDATE
Using the command:
$ GRADLE_OPTS=-Xmx4g ./gradlew jettyRunWar
Trying to build a .war from the pojo returns the cli error:

Increasing the memory allocation value to Xmx6g or Xmx7g still gives this same error.
Furthermore, looking for the file /tmp/makeWar432278342000106527922896081353600/hs_err_pid32313.log that was supposedly created by this error, there seems to not be a directory named "makeWar432278342000106527922896081353600" in my root tmp/ directory, so I'm not really sure where to look for it.

Answer 1

I'm guessing you started it with Gradle. In that case you can do GRADLE_OPTS=-Xmx4g ./gradlew jettyrunwar to start it with 4 GB of memory.
