Extract the zip file into the "plugins" directory of your "eclipse" installation.
Second - make sure you have JDK 1.5.0-beta1 installed.
Third - restart eclipse!
Make sure you change the project's JDK to 1.5.0:
Now - add JDK 1.5 support to your project:
Configuring JDK1.5 folders
(This is the major source of all problems) You must use separate folders for JDK1.5 files. That is, you cannot have JDK1.5 overlap regular source folders, and you cannot have the project as a regular source folder.
Select the source and the output folders in the properties page:
Press "OK" and close the dialog before you do anything else.
Notice that now you Java build path includes the output folder:
Displaying JDK1.5 errors
For some reason you must explicity add JDK1.5 errors to the problems list (make sure the line is checked):
We are ready to go!
Add a java file to the new source folder (you must change the default location):
Version 1.1.0 adds a "recompile" button, which should be used to recompile all JDK 1.5.0 classes. You may need to occasionally recompile the whole project, because the plugin does not currently support dependencies between java files.
You need to run "Window->Reset Perspective" to make the new button to appear. If it does not help, start eclipse.exe with the "-noregistrycache" switch (just once), and then run "Window->Reset Perspective".
Type something in, press save and .....
Enjoy,
