I'm having a problem with Netbeans 8.1 working on Symfony2 project - I don't have any code hints and autocomplete suggestions. It applies to both userland code written by me and autoloaded from vendors.
For example when I want to implement an interface, there's no hint for missing methods. I don't even get autocomplete for $this.
I already tried to clear cache directory with no success.
My Netbeans info:
Product Version: NetBeans IDE 8.1 (Build 20151231-debian-8.1)
Java: 1.8.0_111; OpenJDK 64-Bit Server VM 25.111-b14
Runtime: OpenJDK Runtime Environment 1.8.0_111-8u111-b14-2ubuntu0.16.04.2-b14
Running on Ubuntu 16.04.1 LTS
Perhaps someone had that problem?
I had this problem when I excluded vendors directory in Netbeans project properties. I did it when I wanted Netbeans to use code sniffer. Maybe you'll find it helpful information.
Upgrading to Netbeans 8.2 solved the issue (I'm not sure if it would not work with reinstallation of Netbeans 8.1).
I had to download new version from https://netbeans.org/downloads/index.html because it was not available through apt.
