FileCollectionSnapshotImpl cannot be cast OutputFilesSnapshot


(andrey.yegorov) #1

I’ve started getting this error and cannot find a reasonable way to understand what’s going on there. I’d appreciate any pointers to help understand and resolve this. I am using gradle 1.7.

BUILD FAILED


(mikly.la) #2

I am having the same error. In my case it’s very simple dynamically generated tasks with one file input and one output. All “instances” of it (the difference is which input file) work but one. There is nothing special about the input file for that task, that breaks with this error.

I had to do a full project clean (‘gradle clean’) to get rid of this
