steps:

1. Create a new plug-in project

Launchinfo

Project structure:

2. Interface

Launchplugin.java

Package com.anialy.launch_plugin;

Public interface Launchplugin {public
	void Showonlaunch ();
}

3. Implement

Launchpluginimpl

Package Com.anialy.launch_plugin.impl;

Import Org.eclipse.jface.dialogs.MessageDialog;
Import Org.eclipse.swt.widgets.Display;
Import Org.eclipse.swt.widgets.Shell;

Import Com.anialy.launch_plugin. Launchplugin;

public class Launchpluginimpl implements launchplugin{public

	void Showonlaunch () {
		display.getdefault (). Syncexec (New Runnable () {

			@Override public
			void Run () {
				Long eclipselaunchtime = Long.parselong (
						System.getproperty ("Eclipse.starttime"));
				Long costtime = System.currenttimemillis ()-eclipselaunchtime;
				Shell shell = Display.getdefault (). Getactiveshell ();
				String message = "Eclipse startup time:" + costtime + "MS"; 
				Messagedialog.openinformation (Shell, "Info", Message);}}
		);
	}
	
}

4. Configuration

Plugin.xml

<?xml version= "1.0" encoding= "UTF-8"?> <?eclipse
version= "3.4"?>
<plugin>

   < Extension
         point= "Org.eclipse.ui.startup" >
         <startup class= "Com.anialy.launch_plugin. Launchplugin "/>
   </extension>

</plugin>

Activator.java

Package com.anialy.launch_plugin.startup;
Import Org.eclipse.jface.resource.ImageDescriptor;
Import Org.eclipse.ui.plugin.AbstractUIPlugin;

Import Org.osgi.framework.BundleContext; /** * The Activator class controls the plug-in life cycle */public class Activator extends Abstractuiplugin {//the Plug-in ID public static final String plugin_id = "Lauchinfo";
	
	$NON-nls-1$//The shared instance private static Activator plugin; /** * The constructor * */Public Activator () {}/* * (non-javadoc) * @see Org.eclipse.ui.plugin.AbstractUIPlug In#start (org.osgi.framework.BundleContext) */public void Start (Bundlecontext context) throws Exception {Super.start
		(context);
	plugin = this; }/* * (non-javadoc) * @see org.eclipse.ui.plugin.abstractuiplugin#stop (org.osgi.framework.BundleContext) */Publ
		IC void Stop (Bundlecontext context) throws Exception {plugin = null;
	Super.stop (context); }/** * Returns the shared instance * * @return the SharEd instance */public static Activator Getdefault () {return plugin; }/** * Returns an image descriptor for the image file at the given * plug-in relative path * * @param path the Path * @return The image descriptor */public static imagedescriptor Getimagedescriptor (String path) {return image
	Descriptorfromplugin (plugin_id, path);
 }
}

5. Export as jar (default to Workspce folder)

6. Right-click Project, run

7. Start the test, after the effect
