refresh does not recompile, deleting class files from filesystem and refresh does not recompile. Step 1: go to command prompt, on my windows NT workstation c:\development_sources\del /s /f *.class This deletes all the class files. Now go back to eclipse and try to get eclipse to rebuild the source files. It seems oblivious to the fact that the class files are gone. No matter what you do (short of changing a source file, and saving it, triggering a recompile) you will not get the source files rebuilt. Also, it's not clear what source files get rebuilt when you change one of them and hit save. Ostensibly only the source files that depend on this file. This may be related, but the hierarchy browser can't find the files that subclass a given class and the Type Browser(CTRL + SHIFT + T) can't find the given class (but it's there, and it's not broken). There appears to be a cache and this cache is not in sync with the filesystem, and the type browser is affected and the hierarchy browser (select a class and hit F4) the classes that subclass the given class are not visible.
Not sure if manual deletion of class files is a valid use case. Why are you deleting from the command line instead of doing a full build inside Eclipse? Moving to JDT core for futher comment.
Does a full build create the class files again?
As John asked, deleting the class files is not a valid usecase. 'Rebuild project' & 'Rebuild All' exist in Eclipse if you want to rebuild all your class files.
'Rebuild [all]' etc., no longer exists. All I have is 'refresh'. It seems that 'Rebuild [Project et. al.]' was removed in one of the most recent releases. And actually the refresh does not rebuild anything. Even if you close the Eclipse application, when you restart Eclipse it does not think it needs to rebuild anything. You have to change a file and save, which will trigger a rebuild and all dependencies. But sometimes your sources are read-only, so that's a bit inconvenient. It's nice to be able to delete the class files since you can then use the source code control to do a diff of just the source files. Basically it's convenient for the refresh to function correctly. It should notice that the class files are missing and create them I believe. Oh and again, 'Rebuild project' & 'Rebuild All' do not seem to exist any longer in eclipse. I'm running Eclipse Platform Version: 2.1.0 Build id: 200303192032
These actions are available in the perspective top menu, under "Project".
Closing as invalid.
