I would like to set the ivy.default.ivy.user.dir to something other than the default ${user.home}/.ivy2. I can do this on the command line with
ant -Divy.default.ivy.user.dir=${WORKSPACE}/IVYCACHE. But, I would like to have it set without a command line arg. I have tried setting this property in my build.xml, my common.xml and my ivysettings.xml. The strange thing is, that it seems to set the default cache to this path, but the verbose output says that there is no default setting for user.dir, so it uses the ${user.home}/.ivy2 path.
Here is the output when I set the user.dir in my build.xml file. Strangely, it sets the default cache to the path I used for user.dir

Then later, it claims that user.dir is not set anywhere. resolve:

Here is my build.xml line:
<property name="ivy.default.ivy.user.dir" value="${basedir}/ivy2" />
I have tried adding this line to common/ivysettings.xml and common/common.xml with no luck.
I added the exact line that you have specified in the sample build.xml provided in the ivy binary download and could see the artifacts downloaded in ivy2 subfolder within the samples folder.
...
<property name="ivy.jar.file" value="${ivy.jar.dir}/ivy.jar" />
<property name="ivy.default.ivy.user.dir" value="${basedir}/ivy2" />

I am using ivy 2.2 and ant 1.8.2. Can you check if the same works for you?
[Edit]: From the docs,
Actually all ant properties are imported into ivy variables when the configuration is done (if you call ivy from ant). This means that if you define an ant property after the call to configure, it will not be available as an ivy variable.
The environment variable ANT_OPTS allows to set jvm parameters. So you may put to your ANT_OPTS the same command line argument you invoke 'ant' shell script with. E.g. under m$ windoozer:
ANT_OPTS=-Divy.default.ivy.user.dir=C:/IVYCACHE
