It looks like you can build java soe's using the linux version of the Enterprise SDK. You have to run the setup script on linux to unzip all the files correctly (not sure why that's an issue but the ./Setup fails on mac) but once it's unzipped, you can copy the enterpriseSdk directory over to mac and complete the rest of the setup just like you would on linux (ie install-maven-artifcats.sh etc).
Only limitation is I think you won't be able to JUnit tests on mac but you can still package and deploy the soe file
