Plugin eclipse auto start in product

Question

I am trying to create a plugin that loads different resources taken from the loaded project. I am trying to register to ResourceChangeListener of the workspace in an early stage

Answer 1

You should investigate having a workspace save participant to handle situations before your plug-in is started normally. Few plug-ins are important enough to warrant always starting up that early without any user involvement.

Answer 2

If you want to know the resources (i.e. projects) that are open in a workspace, you can just get the IWorkspace and look at the project contained in it.

IWorkspace workspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot rootResource = workspace.getRoot();

Then you should be able to just traverse this tree structure to find out about all the resources. Hope this helps.

Here are some resources:

• Resources and File System
• Resource Changes in Eclipse

Answer 3

You can try to use the "org.eclipse.ui.services" extension point as follows:

<extension point="org.eclipse.ui.services">
  <sourceProvider provider="com.plugin.YourClass"></sourceProvider>
</extension>

YourClass is a class extends org.eclipse.ui.AbstractSourceProvider

Then your plugin will startup very early!
