No sketch folder property in build properties

[stevemarple]

build.source.path contains the absolute name of the sketch .ino file. No property exists which defines the sketch folder. This is required for recipes which need to reference files within the original sketch folder.

The closest available is build.path (/tmp/...) but when referencing files in there the timestamp changes which forces compilation to be run even when not required.

Are you sure? build.source.path is part of build properties since first release. See https://github.com/arduino/arduino-builder/blob/master/src/arduino.cc/builder/setup_build_properties.go#L98-L104
This is visible even when running -dump-prefs (the first command the IDE runs when you compile)
Can you add some more details and possibly share your platform.txt?

build.source.path was what I expected to use, dumping prefs I get the .ino file, not its folder.

build.source.path=/home/mango/marple/work/arduino15/sketches/sketch_sep24a/sketch_sep24a.ino

I'm using the standard AVR platform.txt file from an unmodifed version of arduino/Arduino (commit 435fc323e0ab3b03bc5835e5309b5022bf57388a)

Ahh you're right. I mistakenly set it to the sketch file instead of its folder. Fixing it right now

Ok, fix will be available with next IDE hourly, which is being built http://www.arduino.cc/en/Main/Software#hourly
