Symfony installation in Eclipse - eclipse

Question

I tried to install the Symfony plugin for Eclipse Indigo, but it gives an error:
Cannot complete the install because one or more required items could not be found.
Software being installed: Symfony Feature 1.0.94.201305191237 (com.dubture.symfony.feature.feature.group 1.0.94.201305191237)
Missing requirement: Composer Eclipse UI Plugin 1.0.2.201402150144 (com.dubture.composer.ui 1.0.2.201402150144) requires 'bundle org.eclipse.e4.ui.di 0.0.0' but it could not be found.
Cannot satisfy dependency:
From: Composer 1.0.2.201402150144 (com.dubture.composer.feature.feature.group 1.0.2.201402150144)
To: com.dubture.composer.ui [1.0.2.201402150144]

To: com.dubture.composer.feature.feature.group 1.0.2
I have to install some additional things before I can install this one. Where can I find them?

Answer 1

You can get the composer plugin on the official eclipse website's marketplace.

Answer 2

Base on your update to Kepler version:
After installing Eclipse Kepler make sure you install the PHP Development Tools (PDT) Run Time Feature and PHP Development Tools (PDT) SDK Feature (all should be version 3.1.1 or higher)
Next you can install the Symfony Feature by following this instruction Help>Install new software; Click Add in the window set Name as Symfony Plugin and the Location as http://p2-dev.pdt-extensions.org/; By pressing OK through the listed plugins select Symfony and other needed plugins like Doctrine, ...
Hopefully this will help you
