[Building Sakai] help compiling pack-demo

Wed Nov 12 18:50:58 PST 2014

Hi All,

I solved one problem I was having with compiling locally. When I was forced
to upgrade to Java 1.7, in itself not a bad thing, Java was still pointing
at 1.6, two installations on my Mac. I tried changing JAVA_HOME, making new
symbolic links, all kinds of stuff and I think I made it worse. But then
from a Stack Exchange article I saw a bit about man java_home. From that I
got the following which worked like a charm:

export JAVA_HOME=`/usr/libexec/java_home`

So if you have a Mac that is at least a couple of years old when Apple was
still installing Java 6 by default, and you are upgrading to Java 7 or 8, I
hope that tip saves you a lot of time.

After solving that problem, compiling pack-demo is still failing for me.
Running
mvn clean install -Dmaven.test.skip=true -P pack-demo

When it failed, maven suggested I run with the -e option to get a fuller
error message, which I did and got the output below.

Any suggestions?

Thanks,
Neal
