Suddenly occured error

[Minkyu Kim]

Hello,

There was nothing wrong when I worked on it until yesterday.

But when I went to work today and built it, an error like the picture appeared.

I can't guess the cause at all.

Reimporting the project or deleting the IDE and installing it anew does not resolve it.

 

How to solve it?

This may help:

* create new Eclipse workspace (empty folder)

* import your project into that workspace
