java - Eclipse not recognizing imports in same project -


from time time, eclipse (indigo) complains classes in projects cannot resolved type. shows class in popup list, clicking import (see image) not add import statement! if add manually, doesn't recognize (and underlines import package).

  • this happens in projects.
  • unresolved types in same project! (not in other dependencies)
  • cleaning project resolve this, temporarily.
  • my application consists of multi-module maven based projects.
  • all projects maven-based.

not recognizing imports

right click on project name ->maven ->update project
