Adding external libraries in NB 8+

I’m adapting an old, NB Platform project (6.9 era) to 8.2.

So I’ve just installed 8.2, I open my project, and it complains that there’s libraries missing.

Not a problem, been here before..

So Project Properties->Libraries tab….

Huh… No “Add Jar” option..

Search google. “Netbeans 8 add libraries” returns nothing but a but ton of links how to add libraries to earlier versions on NetBeans… And they
all say the same thing, Click ‘Project Properties”, use the Libraries tab, click Add jar….

Except, I don’t have that option.. It’s not even an unavailable, grey’ed out option. “Add Project” doesn’t appear to be the answer,
“Add Cluster” feels incorrect...



I must be missing something easy, but I sure can’t seem to find a quick answer…
All I want to do is add back j3d.

Would some kind soul please point me in the right direction?

Thanks!
