Dear Bazel Community,

After a few years of not working on AOSP based projects, I wanted to try out the new Bazel build, which (according to my predictions) should have been in a usable state by now.

So I was very surprised when I saw the short message on source.android.com that the Bazel build transition was cancelled.

I have seen at least some of the AOSP team members post on this list, so I was hoping to learn more about why the transition was stopped.

Were there technical issues with Bazel that made it a bad fit for AOSP?

Or were there some other not necessarily technical challenges (e.g. the Bazel based build could not offer enough advantages for the developers over the current Soong + Kati + Ninja based setup)?

Can we expect a post-mortem talk at BazelCon 2024?

Thank you for any information that you can share.

Kind regards,
Gergely

It looks like banners around source.android.com say now that the migration is halted, not canceled.

But I do recall before that the banner did say that the project was cancelled.

My guess is lack of funding.

Gergely is right: the migration has been cancelled.

Android chose not to continue with its migration to Bazel due to a review of Android business priorities, not due to shortcomings of Bazel or Android itself.
