Not able to test RCP application using "EclipseLibrary"/Could not find "EclipsePlugin"

[Theresa Sebastian]

Hi all, I am beginner at using robot framework for testing RCP application in a remote Linux host. The robot installation and testcases are in a different Linux machine, not in the machine where the application is running. I have some (basic) questions and would highly appreciate any help or input provided:

1) If I understood correctly, "Eclipse Plugin (Robotframework Eclipse Library plugin for SWTBot update site)" should be installed with the RCP application, on the other hand "Eclipse Library (eclipselibrary-x.x-with-dependencies.jar)" should be placed with robot-testsuite under lib folder. Is that correct?

2) Unfortunately I could not locate the "Eclipse Plugin (Robotframework Eclipse Library plugin for SWTBot update site)" as the link provided installation guideline seems broken. Would it possible for someone to point me to the plugin file? I could find only the source file here: https://github.com/lcarbonn/robotframework-eclipselibrary/tree/master/org.lcx.robotframework.swtbotplugin

3) I am trying to execute a robottest from command-line as follows:   "robot --pythonpath <path-to-eclipselibrary-0.21-with-dependencies.jar> TC_xxxx.robot".
However I get the error 
"Importing library 'EclipseLibrary' failed: ModuleNotFoundError: No module named 'EclipseLibrary'".  

Why robot is not able to find the eclipselibrary although it's added to python path?  There is no IDE installed for robot tests currently. Or is it necessary to install an IDE/Eclipse in the machine along with robot?

Many thanks in advance.
