[SOLVED] Particle CLI trouble with "Ethernet" not in scope

[Adam42]

[Start]: I am using the Particle CLI to compile code from the command line.
particle compile photon --target 3.1.0

[Problem]: However, I am getting an error where Ethernet is not recognized and it is blocking compilation.

[Repeatable?]: This error does not occur when I compile using the Particle Workbench extension in VS Code.

[Code]: Here is the code file I am compiling with Particle CLI

#define CLOUD_CHECK_MS 5000

SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(AUTOMATIC);

SerialLogHandler logHandler(LOG_LEVEL_WARN, {{"app", LOG_LEVEL_INFO}});

long now = 0;
long lastCloudCheck = 0;

void setup() {
  System.enableFeature(FEATURE_ETHERNET_DETECTION);
}

void loop() {
  now = millis();
  if(now - lastCloudCheck > CLOUD_CHECK_MS){
    lastCloudCheck = now;
    if (WiFi.ready() || Ethernet.ready()) {
      Log.info("Internet OK");
    }
  }
}

@Adam42

particle compile photon --target 3.1.0

This might be the reason
There is no stock support for Ethernet on the Photon.

However, in the topic tags you have selected Argon (which would support Ethernet)

Which is it?

[Adam42]

Oh my goodness. The Shame…

I’m using an Argon

particle compile argon --target 3.1.0
works without errors

Thank you @ScruffR
