Merge remote-tracking branch 'aosp/upstream' * aosp/upstream: Support checking syntax of generated Blueprint files Always emit rules for tests and add phony to run them Bug: 155628860 Bug: 156428456 Test: treehugger Change-Id: Ia0e0c8d8d07489c945d4e03d039273cc3f597ac0
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.
