Thank you to everyone for the help.
I was following the instructions on the Moodle docs. Setting up Eclipse. Because I was not 100% sure on the programs they offered I went to the Eclipse Marketplace, searched 'php' and it gave me 68 results!
The whole Setting up Eclipse needs to be re-done.
- Installing plugins need to change to PDT
- General and PHP Settings is for PHPeclipse
- SSH2, CVS Settings and Checking out code has changed to Git
I'll firstly learn how Git works before I try to add it to Eclipse. Branches everywhere
I'll try re-writing the 'Installing plugins' section tomorrow. I don't know enough to write anything else.
