Your -Xms value is wrong (missing the unit value, "m") and normally
maven will blowup if you try to run it with incorrect Java opts:

Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

So I don't think you are setting your MAVEN_OPTS correctly, you need
to export them with:

export MAVEN_OPTS='-Xms128m -Xmx796m -XX:PermSize=64m -XX:MaxPermSize=172m'

I normally put this in my shell startup script.

Looking at the wiki page:

https://confluence.sakaiproject.org/display/BOOT/Development+Environment+Setup+Walkthrough

it seems this page is missing the export. Can someone fix this please
(I can't edit the page).
