Package doesn't exist error in intelliJ

Question

I\'m trying to use the barbecue barcode printing library. I have successfully added the library to IntelliJ through project structure add library. Then I imported the packa

Answer 1

Maven reimport, rebuild and invalidate caches did not work. I solved it by opening a terminal and executing maven clean install in the root folder project. (IntelliJ was opened and I was able to see the IDE updating and triggering reindexation while maven was doing his job)

Answer 2

I did re-import all maven projects. This worked for me.

Answer 3

Tried all the above approaches, didn't work. Finally running maven clean install solved it!

Answer 4

As someone who only occasionally needs to do Java work, this was very annoying. Inevitably, packages would have been added since the last time I ran our server inside IntelliJ and it would fail to build. I found what seems to be an easier solution: just don't build within IntelliJ. Build from the command line via Maven, then make sure that the run configuration does not list Build as a "Before launch" task.

Answer 5

If you do not want to destroy .idea, you can try :

• open Project Structure > Modules
• unmark the java folder as a source folder
• apply / rebuild
• then mark it again as a source folder
• rebuild

Answer 6

If you are trying the suggested ways and still no chance, be sure about your order:

1. Delete your .idea/
2. Invalidate and Restart Cache afterwards
3. Import maven projects from your maven tool

If you did not invalidate and restart cache just after deleting your .idea/, Intellij keeps generating it and that was keeping error in my case.
