Eclipse does not automatically compile a solution for Java files

Some time ago, the eclipse does not automatically compile Java files problem, on the internet for a long time, finally solved the problem, and now the solution to this problem summed up.

1. See if Project-Build automatically has a hook on it? If not, after the check, clean, restart eclipse

2. See if there are any unused jar packages in your lib and see if there are any errors in your. classpath file.

3, this is the most important point, there is a problems view to see if there is no error message about this item, generally there is the words: The project cannot be built until build path errors is resolved and then the following prompt u Nbound classpath, usually delete these paths in. classpath. Of course, different error messages have different solutions
