IntelliJ doesn't display compilation errors in editor for Gradle project

I tried to figure it out using a google search but couldn't find any articles that match my question. When I import a Gradle project into IntelliJ (.ipr), I don't see IntelliJ reporting compile-time errors when I add content. This severely limits my use of IntelliiJ, such as adding import statements for classes. What should I do or configure so that IntelliJ starts reporting compile-time errors when I add content?
