Task Inputs cause FileNotFoundException

Strange exception gets thrown on OSX. The same build works find on Linux. With a quick look it seems that org.gradle.api.internal.changedetection.state.DefaultFileCollectionSnapshotter#snapshot doesn’t check if the file exists or is readable before trying to create the hash of it.

org.gradle.api.UncheckedIOException: Failed to capture snapshot of input files for task 'buildDocsHtml' during up-to-date check.  See stacktrace for details.

Is this something new (2.7-rc-1)?

What are the permissions of /home/tester/workspace/encodings/__init__.pyc and are they different between Linux and OSX?

Nope, I saw it happening in 2.3 and 2.6. It’s strange because it only happens on the CI box. I can’t get to the file before the job finishes and deletes the workspace. I’ll see what I can do to get the permissions of the file. I ended up solving the problem by excluding **/*.pyc from task inputs.
