Hi,

My system :
OS : Windows XP SP2
Eclipse : 3.2.2
Spring ide for spring 2.0.2

My problem :
After installation of spring-ide for spring 2 everything worked well, I had auto completion in bean ids and classes in my config files.
But since 2 days I have the following error at eclipse start up :
org.springframework.ide.eclipse.core was unable to load class org.springframework.ide.eclipse.core.internal.proj ect.SpringProjectBuilder.

with the following stacktrace in the log :
java.lang.ClassNotFoundException: org.springframework.ide.eclipse.core.internal.proj ect.SpringProjectBuilder

It seems that you're running a mixup of Spring IDE 2.0 milestone releases.

So please delete all Spring IDE-related features and plugins (starting with "org.springframework.*") from your local Eclipse installation and reinstall milestone 3 via the update manager.
