Arduino Command Line Interface - How to change boardsmanager.additional.urls

Question

I am building a Travis CI job to test my Arduino Library and it needs to install external board definitions.

Is there a way that I can set the boardsmanager.additional.urls from the command prompt like it would have been done in the Preferences window?

Or should I create preferences.txt file? (If so where does that live in a Linux environment)

• James Waldby - jwpat7: The location of preferences.txt is shown near the bottom of the preferences page. It takes two or three clicks to open it in gedit.

Found the solution:

arduino --pref "boardsmanager.additional.urls=http://arduino.esp8266.com/stable/package_esp8266com_index.json"

• per1234: Note that since Arduino IDE 1.6.4 preferences set via --pref are only saved if you also use the --save-prefs option. See: github.com/arduino/Arduino/blob/master/build/shared/…
