.pioenvs caching breaks strange behavior on 2nd run

[nargetdev]

Description of problem

The first time I run $ pio run my project builds just fine and generates appropriate things in .pioenvs folder. The second time I $ pio run new things will be generated in .pioenvs which cause many compile errors.

Specifically, on the second run, it appears to be pulling in an entirely unrelated library (one built for a different platform entirely).

This is easy enough to cope with as follows: $rm -rf .pioenvs && pio run
effectively causing every run to be the "first" run and allowing me to work as normal.

Anybody else seen this?

Configuration

Operating system: OS X

PlatformIO Version (platformio --version): PlatformIO, version 2.9.1

Steps to Reproduce

1. Import Arduino project with board Due (using Arduino libraries folder)
2. run $pio run
3. run $pio run again

Actual Results

.pioenvs populates with "grbl" library on second run

Expected Results

.pioenvs stays the same after first being generated

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:due]
platform=atmelsam
framework=arduino
board=due

[platformio]
src_dir=.
lib_dir=~/Documents/Arduino/Libraries

Source file to reproduce issue:

#include <Arduino.h>

 // Simple demo of three threads
// LED blink thread, print thread, and idle loop
#include <FreeRTOS_ARM.h>
// Redefine AVR Flash string macro as nop for ARM
#undef F
#define F(str) str

const uint8_t LED_PIN = 13;

volatile uint8_t count = 0;

// handle for blink task
TaskHandle_t blink;

//------------------------------------------------------------------------------
// high priority for blinking LED
static void vLEDFlashTask(void *pvParameters) {
  pinMode(LED_PIN, OUTPUT);

  // Flash led every 200 ms.
  for (;;) {
    // Turn LED on.
    digitalWrite(LED_PIN, HIGH);

    // Sleep for 50 milliseconds.
    vTaskDelay((50L * configTICK_RATE_HZ) / 1000L);

    // Turn LED off.
    digitalWrite(LED_PIN, LOW);

    // Sleep for 150 milliseconds.
    vTaskDelay((150L * configTICK_RATE_HZ) / 1000L);
  }
}
//------------------------------------------------------------------------------

  xTaskCreate(vPrintTask,
    "Task2",
    configMINIMAL_STACK_SIZE + 100,

  // should never return
  Serial.println(F("Die"));

}
//------------------------------------------------------------------------------
// WARNING idle loop has a very small stack (configMINIMAL_STACK_SIZE)

    count++;
    interrupts();
  }
}

Hello, I have an appropriate workaround for the time being. This could be scripted easily and does not break Arduino compatibility.

Firstly:
Remove lib_dir=~/Documents/Arduino/Libraries from platformio.ini

The script:
Regex search for includes of the following pattern.. #include <FreeRTOS_ARM.h>
Find those folders in ~/Documents/Arduino/Libraries and copy them to lib ONLY INCLUDING src subdir.

Shall I script this, and add the appropriate option in the Atom IDE "import Arduino IDE project" module?

@valeros please add these 3 libs to PlatformIO Library Registry https://github.com/greiman/FreeRTOS-Arduino/tree/master/libraries

[valeros]

These libs are in our library manager now:
http://platformio.org/lib/show/324/FreeRTOS_ARM
http://platformio.org/lib/show/323/FreeRTOS_AVR
http://platformio.org/lib/show/322/SdFat
