Plug-in development for eclipse-startup time

The author has an eclipse-optimized chapter in the book on "Deep understanding of Java Virtual machines" this evening, which involves the development of plug-ins for Eclipse startup time detection

So turned over the information, but also developed a plug-in

It was started after development.

The start-up time is more than 13s, then I developed the process for everyone to reference

The first step creates a new plug-in project file

Generate an activator in the second step tick

The third step is to write a Showtime.java file

Package com.developer.showtime;

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

public class ShowTime implements istartup{

@Override
public void Earlystartup () {
Display. Getdefault (). Syncexec (New Runnable () {

@Override
public void Run () {
TODO auto-generated Method Stub
Long eclipsestarttime = Long.parselong (System.getproperty ("Eclipse.starttime"));
Long costtime = System.currenttimemillis ()-eclipsestarttime;
Shell shell = Display.getdefault (). Getactiveshell ();
String message = "Eclipse start in" + Costtime + "MS";
Messagedialog. Openinformation (Shell, "information", message);
}

});
}

}

This is my own.

Found an error

Add one after bundle-symbolicname:com.developer.showtime; singleton:=true

Configuration under Plugin.xml

<?xml version= "1.0" encoding= "UTF-8"?>
<?eclipse version= "3.5"?>
<plugin>
<extension point= "Org.eclipse.ui.startup" >
<startup class= "Com.developer.showtime.ShowTime"/>
</extension>
</plugin>

You can now run as---eclipse application, which launches a new eclipse and runs the plug-in, and then you can export the plugin after success.

Do you want to make a plug-in like this? Give it a try.
