I am using Eclipse 3.4.1 Build M20080911-1700
I have tried to change the classpath directories for jar and the source directory using the Project Properties -> Java Build Path -> Libraries Tab or Source Tab. When I click OK button and then return to the properties page, my changes were not applied.
I have to resort in the work around by manually changing the eclipse “.classpath” project settings file.
Any ideas?
Is the .classpath file checked into source control? You may not be able to change it if you don’t have it checked out.
