Log Message:
Update devel/gradle to 4.3.1.

This bug-fix release addresses several regressions in Gradle 4.3.

- Gradle 4.3 introduced an improvement where an error in resolving a
  module from one repository would prevent Gradle from searching for
  that same module in subsequent repositories. However, the change to
  abort searching repositories on all unrecognized errors proved to be
  too aggressive. With 4.3.1, only repository timeout errors will
  prevent Gradle from searching for a module in a subsequent repository.
- Moreover, the connection and socket timeouts for HTTP/HTTPS requests
  have been increased to 30 seconds.
- This version of Gradle also removes an overload of
  TaskInputs.property which caused statically compiled plugin code to
  use the wrong method when calling TaskInputs.property(..., null).
- Finally, when using --scan the build scan plugin is applied before
  other plugins to avoid rendering a warning message.
