I consistently faced the following error while building latest trunk and to
work around, I had to set MAVEN_OPTS=-Xmx512m in my environment. Is it
because there are just a lot of things getting built in the same reactor
requiring more memory?
I'd say that's very likely, also note that an OOM in PermGen means the JVM
has exhausted
its allocated space for class instances (ie. too many classes and/or proxy
classes loaded).
There's also an issue wrt. the default maximum heap - depending on which JDK
release you
use (and even the OS) this can vary from being ~64mb to being half of the
physical memory.
So setting your MAVEN_OPTS to a reasonably large maximum sounds reasonable
to me
if you want to build the whole project tree at once.
If the build does require higher than usual memory, should this not be
set in build.xml before execing mvn?
