For now you can get around the problem by adding the correct definition of ESPTOOL_COM on the command line or in your project config.mk. Fix will come in next version.

Can you please provide example on your setting of EXCLUDE_DIRS and a false positive from that?

The problem here is your declaration of EXCLUDE_LIBS. This must be a strict regexp, you have both trailing spaces when setting the variable and += will always add a space...

Well, actually I guess the removal of spaces could be done automatically in makeEspArduino as you would normally not (and shouldn't) use spaces in path names. Anyhow, glad you got...

Ok, that was an ugly prebuild thingy in platform.txt. Will fix

Finally got around to fix this. Please check latest version.
