After I clean a project in eclipse I don't see the class files generated in the output folder "bin" although there's no build error, what can I do to make it regenerate the class files?
thanks
A:
Under the "Project" menu, see if the option "Build Automatically" is checked.
Edit: Have you checked this on Eclipse or on a file browser? Sometimes Eclipse takes a long time to refresh changes in the file system. Force a refresh by right clicking the bin folder and clicking on "Refresh" on the contextual menu.
Edit: Check your build path, try reconfiguring it from scratch, I don't know if this can help, but who knows...

yes it is, I tried unchecking and checking again, but still nothing.

I checked on the filesystem.

That's odd, there might be something wrong with your Eclipse installation. What JRE are you using?

I downloaded Java SE development Kit 6, which had JRE bundled with it I think.

Make sure you have Build Automatically option turned on as shown:

already tried, but still nothing. it already happened with me before and what helped is waiting an indefinite amount of time till it regenerates them again, but I need them to be regenerated without delay.

That is strange. Edit one of the source files in your projects and save. (add a blank line for example) and see if it generates .class files.

It might be that your project is configured to write classes to somewhere other than ./bin

at first it was configured to do so, but I changed the classpath to include bin.

Huh? The classpath has got nothing to do with where the classes are written (at least not explicitly - the project will automatically include its "output directory" on its classpath). If you've explicitly added bin to your classpath, this might be what is confusing it?

when you create a project in eclipse a .classpath file is generated. it includes the source and output paths, and yes I added it manually.

I know; I'm an Eclipse user. Having to futz with that file manual sounds fishy to me. I've been using Eclipse since 1.0 and have probably hand-edited that file, like, twice in that time. See if re-creating the project helps. (i.e. backup your .project and .classpath, remove the project from Eclipse, delete the .project and .classpath files from disk, and re-import the project into Eclipse)

Yeah at the end that was what I did, wasn't worth spending all the time figuring out what was wrong.
