🔴 DGS codegen plugin 5.0.6 is incompatible with DGS runtime 8.1.1
The DGS runtime was bumped from 4.9.21 to 8.1.1, but the com.netflix.dgs.codegen plugin was left at version 5.0.6. DGS codegen 5.x generates code targeting the DGS 4.x/5.x API surface, while DGS 8.x has a significantly different API (including the move to Jakarta EE namespaces and updated DGS annotations/types).
Root Cause and Impact
At build.gradle:5, the codegen plugin remains at 5.0.6, while at build.gradle:39 the runtime was updated to 8.1.1. The DGS codegen plugin generates Java source files (into build/generated) that import and use DGS framework classes. When the codegen plugin version doesn't match the runtime version, the generated code references classes/methods that don't exist in the runtime, causing compilation failures.
For example, codegen 5.x may generate code importing from com.netflix.graphql.dgs packages with class signatures matching DGS 4.x/5.x, but DGS 8.x has restructured these packages. The codegen plugin needs to be updated to version 6.x+ (e.g., 6.1.0 or later) to generate code compatible with DGS 8.1.1.
This is a separate issue from the javax.* → jakarta.* migration mentioned in the PR description — even after that migration, the generated DGS code will fail to compile due to this version mismatch.
Prompt for agents
In build.gradle, update the DGS codegen plugin version at line 5 from 5.0.6 to a version compatible with DGS runtime 8.1.1. The codegen plugin should be updated to at least version 6.x (e.g., 6.1.0 or 6.2.1) to generate code that is compatible with the DGS 8.x runtime API. Change line 5 from:
id "com.netflix.dgs.codegen" version "5.0.6"
to something like:
id "com.netflix.dgs.codegen" version "6.2.1"
Verify the exact compatible version by checking the Netflix DGS compatibility matrix.

Summary
Upgrades the project from Java 11 to Java 21 and from Spring Boot 2.x to 3.x across
build.gradle, the Gradle wrapper, and the CI workflow. All third-party dependency versions were also bumped to Spring Boot 3 / Jakarta EE compatible releases:The GitHub Actions CI workflow (
gradle.yml) was updated to use JDK 21 (Zulu distribution). The Gradle wrapper was upgraded from 7.4 to 8.5 because Gradle 7.4 does not support Java 21 (class file major version 65).javax.*imports tojakarta.*throughout the Java source code. That migration is explicitly out of scope for this PR and expected as a follow-up. CI currently fails atcompileJavawith the expectedpackage javax.validation does not existerrors, confirming the build infrastructure itself is correctly configured for Java 21.Updates since last revision
