Most build systems have that feature. For example maven has <prerequisites><maven>3.0.0</maven></prerequisites>.\r\n\r\nIf the requirement is not met it should print a _readable_ message like \"You need bazel 0.1.4 or newer to build this, please download and install it from http://...\"\r\n\r\nRationale: The breaking change in tensorflow BUILD files output very cryptic message. There is no change one could figure out he should upgrade bazel from current error message."}}
