Does not connect to brick. #8

Use IP address, it usually takes a couple of minutes. I haven't tried on Windows 7. You need to create a run configuration for Lejos. |
What am I missing? |

Hi, are you using jdk7? Can you ping your ev3 from your pc? Can you open an
ssh connection to it?

Write code to your EV3. Done
I have created a leJOS PROJECT/"Hello World" program.
6.
Create a run configuration. Done
I have a *Run/Debug Configurations* setting. Should it say something
specific.
7.
Enjoy your robot! Error
The leJOS program(Hello World) does not find and is not looking for an
EV3. I do not get an *"EV3 not found"* error. The program is running
on the PC and is printing to the computer screen. That can be a nice option
considering the small EV3 screen, but does not serve the purpose.
What am I missing?

You have to import it:
import lejos.hardware.lcd.LCD;

Editor comments:
Cannot resolve symbol Hello_World
Cannot resolve symbol AfterButton
Cannot resolve symbol waitForAnyPress
On execution: Program prints to the computer screen
3-13-2018 1
Hello_World
Then execution stops and does not print to the screen
AfterButton.waitForAnyPress
The EV3 is never accessed.
I was going to work with Scala. Does all this have nothing to do with
Scala?

Scala is not supported, maybe that's the reason. |

InteliJ IDEA/leJOS plugin does not connect to the Lego brick with Windows 7. The brick is connected by both USB and BlueTooth. But. no application connection is made. Program runs on the PC. Should the IP address be used or the brick name?
