RUM-14050: Fix R8 missing class error for dd-java-agent annotations

kikoveiga · claude · kikoveiga · commit d361e7ebd0ec · 2026-07-02T18:50:19.000+01:00
When dd-java-agent is attached to the Gradle daemon (introduced in #3583 via setup-gradle), it instruments classes at load time for source code profiling, injecting references to datadog.compiler.annotations. SourceLines and datadog.compiler.annotations.SourcePath into bytecode. R8 then sees these references but can't find the annotation class definitions in the build classpath, causing a hard failure in every publish-benchmark-synthetics (and potentially other synthetics) CI job since that PR merged. Add -dontwarn rules for datadog.compiler.annotations.** in the benchmark and kotlin sample proguard files so R8 ignores these agent-injected annotation references.
