Merge remote-tracking branch 'aosp/upstream' * aosp/upstream: Stop writing depfiles from Glob singleton Bug: 159845846 Test: manually check that changes to directories cause glob re-execution Test: second build after a clean does not rerun soong_build Change-Id: I1f257f3f11f70cb407397854fd85292dd0d0b08e
Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a Ninja manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific language to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
