We discovered a bug in Bazel that was causing builds with --remote_download_minimal to download all output artifacts.
A fix has been submitted upstream to the Bazel repository and will be included in the Bazel 9.x release. It will also be cherry-picked back to versions 8.2.0 and 7.6.0.
Users on older versions of Bazel can work around this issue by setting --experimental_remote_cache_ttl to a large value, such as 10000d, with some caveats.
Upgrading Bazel and the related dependencies can sometimes lead to unexpected issues. These issues can range from build failures to runtime errors, and generally, they can be hard to troubleshoot.
So today, we will discuss how to narrow down the root cause of build failures after a dependency upgrade using git bisect.
Do you have an iOS app, or really any Apple-based project, that you want to migrate to Bazel? With this guide I'll show you how to migrate your project, using the Mastodon iOS project as an example.
We will use iOS based rules in the example migration, but similar rules exist in rules_apple for the other Apple platforms, including macOS, watchOS, tvOS, and visionOS.
The completed migration is available in my fork of mastodon-ios. You can follow along with the changes made in the following sections by checking out this commit first. At the end of some sections there will be a link to a new commit that includes the changes mentioned up to that point.
In our last post, we summarized the changes that were in the Bazel 7.0 release. There were a lot of changes though, so it can be hard to determine which ones are impactful to you and why.
Don't worry, we've got your back. In this post we highlight the changes that help BuildBuddy users build even faster!
Bazel 7.0 includes over 3,700 changes since 6.0. It's the latest major release, following the release of 6.0 in December of last year, and it's Bazel's fourth LTS release.
Since there were so many changes, many of them quite impactful, I felt I needed to review them all and provide a nice summary for y'all.
Bazel 6.0 includes over 3,100 changes since 5.4. It's the latest major release, following the release of 5.0 in January of this year, and it's Bazel's third LTS release. Since there were so many changes, many of them quite impactful, I felt I needed to review them all and provide a nice summary for y'all.
Bazel's famous remote caching and remote execution capabilities can be a game changer, but if you're not familiar with how they work, they can be a bit of a mystery.
Well, don't worry. I'm here with to go over the fundamentals of remote caching and remote execution, with a nuts and bolts (or rather actions and spawns 😄) overview of Bazel's remote capabilities.

Bazel 5.0 includes nearly 3,000 changes since 4.2.2. It's the first major release since 4.0 was release in January of last year, and it's Bazel's second LTS release. Since there were so many changes, many of them quite impactful, I felt I needed to review them all and provide a nice summary for y'all. So that's what I did 😄.
