Android gradle构建突然在'：app：mergeDebugResources'上失败，没有错误消息

Question

My gradle build stopped working completely out of the blue. Minute earlier it worked fine. Didn't change anything in gradle config files; as a matter of fact I was only changing application style in XML. Make, clean and run produce:

Execution failed for task ':app:mergeDebugResources'.
> -1

Running gradle with --stacktrace produces:

Executing task ':app:mergeDebugResources' (up-to-date check took 0.031 secs) due to:
Task ':app:mergeDebugResources' class path has changed from 35ff0c585719dc5a2e2e4d58900e722a to 01ad85243d44a7018a6f6b671ff7bf6b.
All input files are considered out-of-date for incremental task ':app:mergeDebugResources'.
Unable do incremental execution: full task run :app:mergeDebugResources FAILED :app:mergeDebugResources 
(Thread[Task worker for ':',5,main]) completed.   
Took 0.155 secs.

Removing build directory didn't help, as well as cache invalidation and restart. Any ideas?

Using Canary (3.0) with build tools version 26.0.0.

Update #1

Running with --info --debug hints:

could not find method google() for arguments [] on repository container.

However, removing google() from config yields:

好吧，事实证明，问题出在res目录而不是main字体，这导致gradle表现得很奇怪。
