Hi @Elliot Hillary
It was that it pointed to the wrong Java version.
I think it would be good to have a better error message for this, and/or add the exact error message text to the FAQ.
If the exact error message text had been in the FAQ, I would probably have found it when I googled the exact error message text.
After fixing the path to version 11 of Java, it got a bit further, but ultimately it displayed no issues for my project.
My project is quite big and I know that there should be issues reported on it, but I suspect that my IT department blocks certain aspects of Java from working.
(I got a popup saying that my IT policy blocked something network-related from working, but unfortunately it does not show up again and I don't remember exactly what it said)
Summary:
Unfortunately I don't think that I can use DelphiLint as long as it relies on Java.
