Any error message?

Yes it should be possible but you need two different starter bat files and
you can't use those at the same time.

When working with QGIS 2.18 plugins my starter bat look like this:
--- qgis2-eclipse.bat
@echo off
set OSGEO4W_ROOT=C:\OSGeo4W64
call "%OSGEO4W_ROOT%\bin\o4w_env.bat"

set PYTHONPATH=%PYTHONPATH%;%OSGEO4W_ROOT%\apps\qgis\
python;%OSGEO4W_ROOT%\apps\qgis\python\plugins
set PATH=%OSGEO4W_ROOT%\apps\qgis\bin;%PATH%

start "eclipse" C:\eclipse\eclipse.exe
-----------

And for QGIS3 plugins:
--- qgis3-eclipse.bat
@echo off
set OSGEO4W_ROOT=C:\OSGeo4W64
call "%OSGEO4W_ROOT%\bin\o4w_env.bat"
call "%OSGEO4W_ROOT%\bin\py3_env.bat"
call "%OSGEO4W_ROOT%\bin\qt5_env.bat"

set PYTHONPATH=%PYTHONPATH%;%OSGEO4W_ROOT%\apps\qgis-dev\
python;%OSGEO4W_ROOT%\apps\qgis-dev\python\plugins;C:\
Users\lauri\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins
set PATH=%OSGEO4W_ROOT%\apps\qgis-dev\bin;%PATH%

start "eclipse" C:\eclipse\eclipse.exe
----------

When adding the interpreters. Try to add the same version python
interpreter that was defined in the starter bat that was used to start
eclipse.
Your python 3 interpreter error message looks like that you tried to add it
when python 2.7 environment was active.



I don't know if it makes any difference but I always have used a bare
Eclipse Platform Runtime Binary (that is without any plugins or development
tools) and then added just Pydev. You also need to install JRE separately.
