[Building Sakai] Sakai CLE build java.lang.OutOfMemoryError: PermGen space

[Simon McLeish]

Because I've had file permission errors in tomcat in the (admittedly fairly
distant) past when I've allowed non-root users write access to the webapps
directory.

Like I said, I did actually run "sudo echo $MAVEN_OPTS" and got back the
right answer, even though the appearance is that the actual values then
failed to be picked up. But it's clear that sudo is not an appropriate tool
for this, whether or not compiling as root is.

Cheers,
Simon
