Answer 1

I know this thread is old but, another solution was to run

$ mvn clean install -Dmaven.test.skip=true

And on IntelliJ do CMD + Shift + A (mac os) -> type "Reimport all Maven projects".

If that doesn't work, try forcing maven dependencies to be re-downloaded

$ mvn clean -U install -Dmaven.test.skip=true

Answer 2

I was getting the same "cannot find symbol" error when I did Build -> Make Project. I fixed this by deleting my Maven /target folder, right clicking my project module and doing Maven -> Reimport, and doing Build -> Rebuild Project. This was on IntelliJ Idea 13.1.5.

It turns out the Maven -> Reimport was key, since the problem resurfaced a few times before I finally did that.

Answer 3

This happened to me when I deleted a folder and then copy-pasted it back to the project.

Right-click project folder -> Rebuild worked for me.

Answer 4

I know this is old, but for anyone else, make sure that the class that's missing is in the same package as the class where you get the error/where your calling it from.

Answer 5

If you are using Lombok, make sure you have enabled annotation processing.

Answer 6

For me - I tried these steps(Invalidate Cache & Restart, Maven Reimport)) but they didn't work. So I deleted the .idea, .settings, and .project folder and tried - it worked.
