Eclipse, I could go on a rant about it but I won’t (maybe another post). I booted up Eclipse today and it decided to throw me an error:

Workbench has not been created yet

It also had some info saying that project x can’t be built etc.

Solution

After trying a few different solutions I found the following worked for me:

  1. Project > Build Automatically (turn off)
  2. Project > Build Working Set > Select Working Set…
  3. Create / Modify a working set to include the project that was missing.
  4. You can turn on Build Automatically now. Everything should be fixed.

Why

Honestly I didn’t fully look into it but it just appears as though the default Build Automatically was skipping project x. By creating a new Working Set it seems to have told Eclipse everything required to stop the error from appearing.
