OfficeFloor is now available to develop within IntelliJ.
While the plugin was originally developed for Eclipse, we have now isolated the functionality into IDE agnostic bundle. This means with a bridging implementation, it is possible to port the OfficeFloor plugin to other IDEs.
However, for now we are content with Eclipse and IntelliJ for OfficeFloor development.
Though if you would like to see OfficeFloor development supported by other IDEs, please get involved!
IntelliJ OfficeFloor Plugin is available at https://plugins.jetbrains.com/plugin/13151-officefloor
(and in the IntelliJ Marketplace – when using latest IntelliJ version).
