I followed the youtube instruction by Doug Schaefer

step by step, 3-4 times, without uninstalling Eclipse but deleting everything, projects and connections. all with the same results.

before creating an Arduino project
connection to Arduino Uno target was ok. console showing the uno running with previous load output. see attached screen capture.

when I created the Arduino project, the connection disappear.
I get error the" java.lang.NullPointerException" error when I try to execute

I'm running Windows 10

If you can attach your log file at <workspace>/.metadata/.log, it can give a hint of what went wrong. Better put it aside and then recreate the problem, so that a new LOG is created with only this issue.

Thank you, Alex. but I have abandoned the Eclipse C++ Arduino 2.0 plug-in. and installed the Sloeber plug-in. ported some projects from my Arduino IDE and its working so far. Maybe I'll try the Eclipse C++ Arduino 2.0 again later.

I think it's because baudrate.
I have uploaded a sketch to my arduino which uses Serial baudrate 115200, but Eclipse uses something else - 57600 perhaps?
Also, I have set up connection, but launch target dropdown doesn't list it.
