Hi Iain,
Thanks for considering Isis as part of your MSc.
As the other guys have said, this looks like a simple Java heap memory
error. Isis is pretty big, and Maven needs to allocate memory in order
to compile it. The defaults (defined by $MAVEN_OPTS) are not big enough
to compile Isis, hence your problem.
The fix - setting MAVEN_OPTS to a larger value - is pretty standard; but
of course if you haven't seen the error before, you wouldn't necessarily
know how to fix it.
Let us know how you get on with the fixes suggested by Kevin / Mike.
Also, so you know, we do have Isis snapshots available on the Apache
Snapshots repository, at
https://repository.apache.org/index.html#view-repositories;snapshots-group~browsestorage
<https://repository.apache.org/index.html#view-repositories;snapshots-group%7Ebrowsestorage>
. I'm just working on getting an updated archetype there also, after
which I'll provide a page on our site to tell people how to get up and
started using that archetype.
Thanks again for your interest,
Dan

Hi there,
My name is Iain and I'm looking into working with Apache Isis as part of an MSc
project. Unfortunately, I seem to have hit a bit of a snag building the version
that's on the project page (that you can check out using svn). I'm running a
MacBook on OS X Snow Leopard (latest updates installed) with Java version
1.6.0_22. I've tried it multiple times, along with having as few processes as
possible running, but it seems like I get the same error every time. I've not
got access to another machine I can install maven on at the moment so I can't
test that.
I've had a look through this mailing list but can't seem to find any
similar-looking problems. If someone could try and tell me what's wrong here
I'd really appreciate it. If I've omitted any important details just tell me
and I'll do my best :)

My log is as follows (I've just taken what seems relevant as I wouldn't want to
try burying a needle in a haystack!):
