I am not sure why it is still not able to find the org.eclipse.core.resources.ResourcesPlugin class.
The log shows that the ResourcesPlugin is being found but its plug-in activator is getting a null pointer exception when it tries to get the IContentTypeManager.
The content type manager is provided using OSGi declarative services but you have not included org.apache.felix.scr which deals with this.
So at a minimum you need to include org.apache.felix.scr and start it in the <configurations> section:
<plugin id="org.apache.felix.scr" autoStart="true" startLevel="2" />
