Latest nightly does not upload compiled sketch

[BbIKTOP]

Latest nightly build failed to upload sketch into esp8266

To Reproduce
Create any/empty sketch, then upload it

Expected behavior
Sketch shall be uploaded but it's not

Screenshots

Starting upload
Uploading project "test" with "ESPTOOL"
Starting reset using DTR toggle process
Continuing to use "/dev/cu.SLAB_USBtoUART"
Ending reset

Additional context
When I launch the failed command from the command line (bash) it works just fine:

Here's the sketch:

viktor@imac:~/eclipse-workspace/test $ cat test.ino
#include "Arduino.h"
//The setup function is called once at startup of the sketch
void setup()
{
// Add your initialization code here
}

// The loop function is called in an endless loop
void loop()
{
//Add your repeated code here
}

As expected, there's an empty argument passed. I've added the arguments print to the python script , here it is:

Number of arguments: 21 arguments.
Argument List: ['/Applications/Eclipse.app/Contents/Eclipse//arduinoPlugin/packages/esp8266/hardware/esp8266/2.5.2/tools/upload.py', '--chip', 'esp8266', '--port', '/dev/cu.SLAB_USBtoUART', '--baud', '921600', '', 'erase_flash', '--end', '--chip', 'esp8266', '--port', '/dev/cu.SLAB_USBtoUART', '--baud', '921600', '', 'write_flash', '0x0', '/Users/viktor/eclipse-workspace/test/Release/test.bin', '--end']

This issue seems to have a solution in #1073 or #1090.
Any of them includes a workaround.
