How to build a standalone project?

Is there an easy way to build a java robot project on my laptop without being connected to our robot? That is, verify that the code will build without trying to deploy.

At least if you get to the deploy step, you can confirm the code compiles. We do this all the time - if your failure is due to not finding the RIO, you have confirmed your code is syntactically correct and can create a .jar file.
