More difficult way (from sources)

Might be useful during development

Using install script

1. Be inside this project
2. Run bazel run //install -- <installer flags> (--help is available)

Using coursier

Project Views

In order to work on huge monorepos you might want to specify directories and targets to work on. To address this issue, Bazel BSP supports (partly) the Project Views introduced by Google.

Check project view readme for more info.

Tests

End-to-end tests

e2e directory contains end-2-end tests that check various scenarios of server usage.

Tests are marked as manual so they won't be executed on bazel test //...

bazel test //e2e:<test name>_bazel_<bazel version> - to run a specific test (to see all possible tests, check the e2e/BUILD file), e.g. bazel test //e2e:sample_repo_test_bazel_6_3_2

Unit tests

Run bazel test //... to execute all the unit tests.
