What about this collection ?

The update site will contains some plugins:

• Static Import plugin: contribute to the Favorites and add some static import, such as java.util.Collections. This plugin will add a default set of imports. Note: this plugin will not scan for static methods in your project, it will only add a fixed set of static import.

Installation

To install the plugin(s), simply follow theses step:

1. Open Help > Install New Softwares
2. Add https://glhez.github.io/eclipse-plugins (simply paste the URL and press enter, it should work)
3. Select the plugin you want to install

Old plugin

For various reasons, I began to rename my project package from fr.glhez to com.github.glhez. I did not find a simple way to say to Eclipse that the new plugin/feature are superseding the previous one.

TL/DR: old plugin fr.glhez.eclipse.plugins.staticimport / feature fr.glhez.eclipse.features.all must be removed.

If you forget to clean your Eclipse, then the PreferenceInitializer will get called twice which is unneeded.
