Why P2D not working inside Eclipse when i using the processing.core?

After a while, I returned to this task, and the solution turned out to be to specify my own libraries in the project itself.

For those who have a similar problem, I will provide a solution, as well as some additional data.:

Development environment: Eclipse
OPERATING System: Windows 7
Java: SE 17

Decision:

just create a path in your project.:
native/windows-amd64

go here to install all the files from the same folder as in processing.
(processing\core\library\windows-amd64)

in addition, after that, you should definitely add the following libraries to your project:

  1. core.jar;
  2. gluegen-rt.jar;
  3. jogl-all.jar;
