Eclipse Project Red exclamation mark no wrong package _eclipse

Eclipse has a red exclamation mark;

This can be done in general, and the processing method is from the network

1, right key item name BuildPath---> Configure build paht ... , and then there are several tabs above to find a package with a path error in the libraries with a red fork. Modify the current path to the corresponding package in classpath. Then go back to Eclipse and F5 refresh the project.

If you can't, try the clean project.

Project--->clean

If your eclipse project has a red exclamation mark and the libraries does not appear in the Red Fork, I do.

1, first convert Eclipse to markers view, Windows---->show view---->markers

You'll find the error content,
Archive for Required library: ' XXXXXXXX001 ' in Project ' xxxxxxxxx ' cannot to be read or are not a valid ZIP file
2, with Notepad open the project root directory of the. classpath file, find "<classpathentry kind=" Lib "path=" XXXXXXXXX001 "/>" This line, delete

Save, refresh, this error is not, so the red exclamation mark also did not.
