Description David henry CLA 2018-06-20 05:37:41 EDT 
This is a variation on bug 513516 reported earlier.

The platform is defined as Mega2560 (which supports Serial1)
The sketch below reports Serial1 as an unresolved synbol

#include <Arduino.h>
void setup() {
	Serial1.begin(9600);
        Serial1.print("blah");
}

adding the line
extern HardwareSerial Serial1;

solves the problem

Thank you for taking the time to file a bug report about the Arduino component of the CDT project. The Arduino component is no longer maintained and will be removed from CDT 10 (Bug 562498). The final Eclipse CDT version that will include Arduino support is the CDT 9.11 series. 

Please consider using The Arduino Eclipse IDE and plug-ins named Sloeber (https://marketplace.eclipse.org/node/2637354) for your future Eclipse CDT powered Arduino development.
