[Jason-users] Error while installing Eclipse Jason feature

[Alex M. <ale...@gm...>]

Hi!

I am trying to install Jason Feature in Eclipse and I am receiving the
error message:
An error occurred while collecting items to be installed
session context was:(profile=DefaultProfile,
phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=,

Is it OK? I am using Eclipse 4.11 from Spring Tool Suite 4, but I have
checked compatibility checkboxes during feature search and it nevertheless
found the Jason feature, so, the feature should be compatible with my
Eclipse.

When I am trying to access some file, I am getting:

So, maybe that is something not under control of Jason group?
