$ bazel build //:all just works, for any project and any platforms.
- Builds don’t require command-line flags.
- Each target automatically uses correct settings (e.g.
android_binaryuses the right NDK).
- It’s easy to build for multiple platforms.
- Builds scale well, particularly w.r.t graph size and action caching.
Dates are approximate based on our best understanding of problem complexity and developer availability. In 2021 we intend to focus more effort on fewer projects at once. We’ll only set ETAs for actively prioritized work in the interest of accurate expectations.
- This is our main priority for the beginning of 2021.
- This is blocked on Android platforms. We can turn this on with a simple flag flip.
pausedMulti-platform targets NOT STARTED
- Let targets declare that they should build for multiple platforms
- Listed here because of user request
pausedDeprecate and remove
--cpu and related flags
- This is an aspirational goal that falls out of migrating all rules to platforms.
2021An experimental Bazel mode caches cross-platform Java compilation IN PROGRESS (#6526)
- Improves multi-platform build speed
- Underallocated, so progress is slow
