Cannot install without Java being installed

[wtbjim]

Recently when trying to install this I ran into an issue where I was unable to install. In the end, the culprit was that I needed to have Java installed and added to PATH. This is because one of the dependent libraries, node-plantuml requires java as a part of it's installation.

Could this be added to the list of dependencies or called out somewhere in the getting started to make it easier for people who are doing a fresh install? Or perhaps I missed something and there is a way to install without install Java. Thanks!
