See this github issue for an answer.
Your project icon in the PHP package explorer will have a small Symfony logo attached to it. Also, if you open the properties of your project and see the Builders section, you should see a Symfony builder.
The plugin cannot infer types of synthetic services - services which are dynamically injected during runtime. For those cases, there's a preference page called Services where the id/class mapping can be stored. After that, the plugin should complete the service properly.
The plugin indexes services and annotation during the build process. Try to clean the project (project -> clean). If it's still not working, check if the project has a Symfony nature.
Check your build-path - project -> properties -> PHP build path - and ensure that all your source folders are in the build path. Also make sure that none of your sourcefolders are excluded.
Eclipse can be started with various debugging options. This can be turned on/off for each installed plugin independently. To debug the symfony plugin, create a file called .options in your Eclipse installation folder. The file should contain the following lines:
org.eclipse.dltk.core/debug=true com.dubture.symfony.core/debug=true com.dubture.symfony.annotation/debug=true com.dubture.symfony.index/debug=true com.dubture.symfony.ui/debug=trueThen restart eclipse from the commandline with these flags: eclipse -debug .options
Try to reproduce the problem and monitor the commandline - please provide these stacktraces in your github issues.
Eclipse(Mac) / Help(Windows/Linux) -> About Eclipse -> SDK -> Installation Details -> Plugins lists all installed plugins and their version. Note that the Symfony eclipse Feature actually consists of multiple plugins listed on that page.
