OSX: Arduino 1.6.2 path change - avr-g++ not located at the correct place

[jipp]

I tried the following using the plugin version 2.2.0.1 and the nightly build (2.4.0.201504090213) of the plugin.

for OSX the Arduino IDE has changed the path.
1.6.1: /Applications/Arduino.app/Contents/Resources/Java/hardware
1.6.2 and upwards: /Applications/Arduino.app/Contents/Java/hardware

setting the preferences in Eclipse:
using the plugin with OSX with 1.6.1 works without problems
using 1.6.2 and above results in "value must be an existing file" message. The version is detected successfully - but compilation is not working anymore.

I changed the preferences per project to match the new folder structure, but compilation shows the following - the path to the avr-g++ is not correct, while the path to the libraries is OK:

it might be related to the platform.txt:

1.6.1:
compiler.path={runtime.ide.path}/hardware/tools/avr/bin/

1.6.2 and upwards:
compiler.path={runtime.tools.avr-gcc.path}/bin/

looking at the output above the 'runtime.tools.avr-gcc.path' seems to be empty.

I never tried 1.6.2 but the 1.6.3 uses
compiler.path={runtime.tools.avr-gcc.path}/bin/
as ArduinoIDE didn't define runtime.tools.avr-gcc.path it doesn't work
I changed
compiler.path={runtime.tools.avr-gcc.path}/bin/
to
#compiler.path={runtime.tools.avr-gcc.path}/bin/
and now it works.

I made issue arduino/Arduino#2982 on the arduino IDE.
Just for now you can remove the compiler.path from the platform.txt
Note that sam has the same issue.

and teensy has not

I removed 1.6.2 and 1.6.3 from the supported list.
