Handling out of memory errors in builds
----------------------------------------------------------------------------------
If the build process fails with an out of memory error, you should be able to fix
it by increasing the memory used by maven -which can be done via the environment
variable MAVEN_OPTS.

Maven
export MAVEN_OPTS="-Xms256m -Xmx512m"
