java - The project was not built due to "Could not delete '/Help/build/classes/exportFile'.". -


when imported project in eclipse oxygen, gave below error. "the project not built due "could not delete '/help/build/classes/exportfile'.". fix problem, try refreshing project , building since may inconsistent"

googled , got delete contents of bin folder , clean project. there's no bin folder. tried cleaning, still same error. else can done

you found solution yourself, here more informations error.

first, said, search brought answers deleting bin-directory manually solves don't have directory. reason configured project write classes classes-directory (bin default).

the "cannot delete" message appears on windows systems if there process keeping lock on directory or files within. classic reason run application or have explorer window open shows content of directory. closing application/explorer window solves problem. lock keeps staying. way find culprit using sysinternal's processexplorer. allows search using find->find handle or dll. result can clicked on , can forcefully close entry, releasing lock (some programs don't never had problems doing that).

but it's necessary reboot system if can't rid off lock otherwise.
