How to get IntelliJ From making annoying blue popups?

Question

On Mac OSX running the latest JDK, my IntelliJ 9.0.3 pops up these incredibly annoying and persistent windows:

This stuff compiles and runs fine, the JDK is definitely operational on this machine. It should be a java.util.string, not some other apache string. what is this supposed to be, and how do i get rid of it? Thanks!

Answer 1

Found it! In intellij idea 14, go to

settings -> editor -> general -> auto import, and untick 'show import popup', under the java/kotlin/xml/... section.

That will fix it.

My guess is that you have not configured the Java SDK that your project is using.

File -> Project Structure -> Project -> Project SDK, choose one, make sure it doesn't show in red.
