  2. Enabling Kotlin incremental compilation on Buck2This post details the integration of the Kotlin incremental compiler into Meta's Buck2 build system. Key technical contributions include: 1. Integrating with the Kotlin Build Tools API (experimental) for incremental compilation support. 2. Implementing a workaround for shaded vs. unshaded Kotlin compiler dependencies using `jarjar` and later migrating to the shaded compiler. 3. Configuring Buck2's incremental actions to preserve previous build outputs, enabling the incremental compiler to access necessary data. 4. Ensuring the compiler cache is relocatable for distributed builds by explicitly configuring project and build directories. 5. Optimizing change tracking by using Buck2's hash digests of action inputs to provide a list of modified files to the compiler, and generating classpath snapshots for dependency ABI changes. 6. Adapting custom Kotlin compiler plugins to be incremental and accumulate results across multiple compilation rounds to handle partial inputs and avoid output overwrites. 7. Verifying annotation processor functionality, noting that KSP2's built-in incremental support requires no changes, while KAPT would have required more effort.
