You can also have this automatically opened in Xcode by `make open-hotspot-xcode-project` (but note that for repeated runs of this, `make open-hotspot-xcode-project-only` is greatly preferred).

For me, buildtools means "binaries we create to help with the build of the product" (basically specialized compilers).

Generating an IDE project is a different kind of story. Given your question, I checked what the Visual Studio java tool did. It created it's output in `$(HOTSPOT_OUTPUTDIR)/support/ide_classes`. That's not really better. (I think it should go to `$(MAKESUPPORT_OUTPUTDIR)/ide/visualstudio`.)
