How can I make a program I've added to the PATH run from the terminal?

I've followed this question to add eclipse to the path (using ln -s to make a link to /usr/local/bin/eclipse from home download), and when i type

eclipse

I get /usr/local/bin/eclipse, but when I type

into the terminal I get a snap message saying:

'eclipse' not found, but can be installed with: sudo snap install eclipse

I explicitly went the route of downloading the tar file from Eclipse's website to avoid snap. Is this an issue with snap trying to "overide the PATH" or have I not setup eclipse into the path correctly?
