Failed to resolve: support-fragment error when add google architecture component dependency

Question

I want to use Google architecture components in my app, but after updating android studio to version 3.1.1 when I add android.arch.lifecycle:extensions:1.1.1 depend

Answer 1

This just happened to me with a project I cloned from github.

I updated my SDK and buildtools and had to double check all the dependencies to match the buildToolsVersion and the compileSdkVersion from the project.

The error message wasn't very clear when I tried to sync the project, it only gave me a more explicit error when I tried to run and it failed.

Could not find support-fragment.jar (com.android.support:support-fragment:27.0.2).

Good Luck!
