I'm trying to build Nakamura while following
https://confluence.sakaiproject.org/display/KERNDOC/4+Building but I keep
getting out of memory errors. When I build it with the tutorial's
recommended maven settings, MAVEN_OPTS="-Xmx256m -XX:PermSize=256m", I get
the following output after about 8 minutes.
I also tried increasing the memory available to the JVM with
MAVEN_OPTS="-Xms256m -Xmx2048m -XX:MaxPermSize=256m -XX:PermSize=256m
+XX:UseConcMarkSweepGC", but even with 2 GB of heap I get
"java.lang.OutOfMemoryError: Java heap space". Anyone have a solution to
this?
