I don't understand the problem. Please help me.

This kind of problem is very rare but we have the solution, If you are using gradle or maven then first close your project and delete from eclipse (remember don't delete from disk), then delete the files and directories from your project:

1. .settings/
2. .project
3. .classpath
4. .gradle/

then reimport the project in eclipse and you are done. you will no longer face the error like "Errors running builder 'Java Builder ' "
