[eclipse] Does a "Find in project..." feature exist in Eclipse IDE?

yes, but you need to open the global search panel. to do so, press the binoculars icon on the top right corner of the IDE.

you can even filter searches by function identifiers, method scopes an etc...

  • Choose File Search for plain text search in workspace/selected projects
  • For specific expression searches, choose the relevant tab (such as Java Search which allows to search for specific identifiers)
