My android app Gradle build is not syncing, since I updated my android studio to 3.2. I have updated everything in the dependencies and still getting the same error. Here ar
So the problem doesn't necessarily needs to be in your application level build.gradle script (the one you posted). It can also be in the project level one or even in the maven-publish-aar.gradle one (if you have it). This means, you could be using deprecated Gradle features on any Gradle script.
I have updated everything in the dependencies and still getting the same error.
Most likely, the warning will be gone once you identify and replace any deprecated Gradle feature that's causing you this trouble. To do this, it will help you to actually add the mentioned --warning-mode=all flag to your Gradle command line options (on your Android studio compiler settings):
This will print the proper warnings for you to be aware of what are the specific deprecated features your app is using.
In my case (for example), I just added the enableFeaturePreview('STABLE_PUBLISHING') setting on the settings.gradle file and that did the magic (I'm using publishing{}).
Also, I know you asked this near a month ago, but, it might be useful for other people facing the same issue.
