CMake: from local.properties: (not specified); latest from SDK: (not found); from PATH: 3.10.2;

After upgrading to Android Studio 3.1 my project will no longer build, giving me an error pointing to one of my VectorDrawables defined in xml: `Error while processing /Users/richard/project/app/src/main/res/drawable/name_of_drawable.xml : null`

This can be reproduced by download the sample project attached and attempting to build with Android Studio 3.1, the project is also available here:

https://github.com/octohub/StudioBug

I expect the error message to tell me something like "Your drawable is using an unsupported attribute, please remove the attribute or increase your minSdkVersion".

I have also added a screenshot of the unhelpful error.

Here is the relevant Stack Overflow post:

Sorry for the delay getting back to you about this. I believe (after testing using Android Studio Iguana) this is no longer applicable.

This issue remains reproducible using AGP 8.6.0-alpha07

Here is the stacktrace:

The exception thrown is provides slightly more details but doesn't address the bug, although we should improve the error messaging to provide the user with a solution - as this is currently unhelpful for debugging if the <gradient> tag is not wrapped in the <aapt> tag.

Marked as fixed.

Error messaging improved to explain the resource inlining requirement and link to https://developer.android.com/guide/topics/resources/complex-xml-resources.
