Google GSON Dependency not found

Question

I am trying to have GSON in my pom.xml but IntelliJ is telling me that the dependency "com.google.code.gson:gson:2.8.0" not found. I have tried calling the Maven repository but it still is not working. Also ignore the commented out lines.

Here is a copy of my pom file.

Answer 1

I remembered how to do this really quickly. You have to go to File -> Project Structure. Then click the Libraries tab and the green plus. Once clicked select from Maven and then search GSON and find the correct GSON version you want to use from the menu and then GSON dependency will work.

Answer 2

I had the same issue.

Go to File -> Invalidate Caches/ Restart and click the same again.

Android Studio restarts and reloads all your library files.
