Eclipse exclude php files from validation but not build

Question

I have a very simple use case. Eclipse Kepler with PDF. New project with PHP nature.

One file at the root

# test.php
<?php

$fu = new Fu();
$fu->bar();

&

One file in a directory

# vendor/vendor.php
<?php

class Fu {
    public function bar () {

    }
}

&

Both files show an error in the Problems view. I need to exclude all files under vendor/ (recursively) from the Problems view, while keeping the code completion on objects defined under vendor/ (recursively).

Desired result:

• code completion in test.php still works on Fu and all classes defined under vendor/
• the Problems view doesn't show any error or warning on files under vendor/
• the Problems view shows errors and warnings on other files as usual
• the Problems view doesn't depend on the selected element

What I tried:

• removing vendor/ from the Build Path also removes all code completion on classes under vendor/
• Project > Properties > Validation > Enable project specific settings + PHP CodeSniffer Validator settings > Exclude Group > Folder: vendor doesn't do anything at all

Answer 1

You should install latest PDT (3.3.1 is available on marketplace) into your eclipse kepler instance.

This version have special feature: "library dir". This functionality allow you to disable all validators (JS/PHP/HTML/CSS...) on buildpath dir.
