Build Events

The Build Events component configures the Build Event Protocol support.

The main purpose here is the Usage item that copies the build event flags that you can use to stream build events from your terminal to the Build Results UI.

By default, this is --bes_backend=grpc://localhost:8085 --bes_results_url=http://localhost:8085/pipeline. Therefore, if you'd like to examine the build events for any given build locally, run the following command:

bazel build //:gazelle-protobuf --bes_backend=grpc://localhost:8085 --bes_results_url=http://localhost:8085/pipeline

Preferably, this can go in your .bazelrc:

build:bezel --bes_backend=grpc://localhost:8085

build:bezel --bes_results_url=grpc://localhost:8085/pipeline

build:bezel --bes_timeout=5s

build:bezel --build_event_publish_all_actions

bazel build //:gazelle-protobuf --config=bezel

~/go/src/github.com/stackb/rules_proto $ bazel build //:gazelle-protobuf --bes_backend=grpc://localhost:8085 --bes_results_url=http://localhost:8085/pipeline
