1) create Spring Boot project with SB V1.3 and add “Devtools” (1*) to dependencies Seems this step was not necessary for me
2) invoke Help->Find Action… and type “Registry”, in the dialog search for “automake” and enable the entry “compiler.automake.allow.when.app.running”, close dialog
3) enable background compilation in Settings->Build, Execution, Deployment->Compiler “Make project automatically”
4) open Spring Boot run config, you should get warning message if everything is configured correctly
5) Run your app, change your classes on-the-fly
Alternatively, my buddy was able to figure out that you can perform a make on the HTML/JS file (shortcut key is in the IDEA menu, it’s something like a CMD+FN+F9 on a Mac) and that will auto save and do the build/make for you. Not a bad backup option and as my very wise friend Mark pointed out; you can also remap the keys so it’s easier than getting your nuts in a sling around FN+CMD+SHIFT+F9 (on my Mac anyways).
