How to refactor package import in intelliJ

Question

I am plaaning to upgrade joda DateTime api to Java DateTime API in all my classes.

import org.joda.time.LocalDate

to

 import java.time.LocalDate

Is there any way to easily perform this refactoring in intellij so that it will resolve and replaces all usages correctly.

Answer 1

This is not possible, because jodaTime has a different API than the new one from Java 8. IntelliJ has quite good refactoring capabilities, but it can't analyze your application logic and convert method calls from package A to different calls - with other parameters - from package B.

Of course, you can perform a simple "search + replace". After this, you'll get compiler errors, and you have to correct them manually.

Answer 2

You may want to have a look at the Type Migration refactoring feature.

Place the cursor onto the type you want to be replaced and hit CTRL+SHIFT+F6.

This is not doing the replacement for the whole project at once but it may help you.
