Listing all external dependencies name, version and licence(s) for target

[aallrd]

Hello,

I have to list all the external dependencies of a bazel built project (envoy), with their name, version and license(s).

I am looking for an output in any format that would list this information for each dependency embedded in the final binary (no tests requirements).

Looking at the envoy repo, it seems all this information is available to the build system: envoy/bazel/repository_locations.bzl

I have a bazel build command used to produce this envoy static binary with many 'filters' and 'options':

bazel \
  --output_base=output_base \
  build \
  --define google_grpc=disabled  \
  --@envoy//bazel:http3=False     \
  --@envoy//source/extensions/wasm_runtime/v8:enabled=false \
  [...]
  @envoy//source/exe:envoy-static

I have tried to play with the query command of bazel but I am not able to get what I want using it.

Do you know a way to get the output I need ?

Thank you.

we're working on various solutions for that with code in rules_license. But we're still working on the glue to help link back to the licenses of projects that come in auto-magically through maven deps and bzlmod.
