## Summary
Moves the build onto the Spring Boot 4.2 / Spring AI 2.1 release candidates.
```diff
gradle/libs.versions.toml
-spring-boot = "4.1.1"
+spring-boot = "4.2.0-RC2"
-spring-ai = "2.0.1"
+spring-ai = "2.1.0-RC2"
-mcp-sdk = "2.0.1" # pin + mcp-bom library
removed
-opentelemetry-logback-appender = "2.28.1-alpha"
+opentelemetry-logback-appender = "2.33.1-alpha"
build.gradle.kts › dependencyManagement.imports
-mavenBom("io.modelcontextprotocol.sdk:mcp-bom:2.0.1")
mavenBom("org.springframework.ai:spring-ai-bom:…")
```
Two follow-on changes go with the bump:
- **MCP SDK pin dropped.** `mcp-bom` 2.0.1 was declared ahead of
`spring-ai-bom` to lift the SDK past what Spring AI 2.0.1 shipped. Spring AI
2.1.0-RC2 depends on SDK **2.2.0-M2** itself, and under the plugin's "first
declaration wins" rule the old pin would have held the SDK back at 2.0.1.
Without the pin, `mcp`, `mcp-core` and `mcp-json-jackson3` all resolve to
2.2.0-M2.
- **OTel logback appender aligned with Boot's OpenTelemetry 1.67.0.** Boot
manages `opentelemetry-api`/`sdk` but not `opentelemetry-api-incubator`, which
follows the appender. With 2.28.1-alpha the classpath mixed SDK 1.67.0 with
incubator 1.62.0-alpha:
```text
OpenTelemetrySdkAutoConfiguration.openTelemetrySdk
OpenTelemetrySdkBuilder.build (sdk 1.67.0)
SdkConfigProvider.<init>
DeclarativeConfigProperties.get (api-incubator
1.62.0-alpha)
→ NoClassDefFoundError: io/opentelemetry/api/internal/ConfigUtil
```
2.33.1-alpha is built against 1.67.0 and brings
`opentelemetry-api-incubator:1.67.0-alpha`. `dev-docs/graalvm-native-image.md`
records the new pairing and the error, and `AGENTS.md` records the new versions.
Both RCs are published to Maven Central, so no milestone repository is added.
## Evidence
- **Before** (versions bumped, appender unchanged): `./gradlew build` → 388
tests, **122 failed**. Every `@SpringBootTest` context failed on the
`NoClassDefFoundError` above, and `McpClientStdioIntegrationTest` timed out in
`initialize()` because the spawned jar died at startup.
**After:** `./gradlew build` → **460 tests, 0 failures, 0 skipped**,
`BUILD SUCCESSFUL`.
- The bootJar ships `spring-boot-4.2.0-RC2`, `spring-ai-mcp-2.1.0-RC2`,
`mcp-core-2.2.0-M2`, `opentelemetry-api-incubator-1.67.0-alpha`, and
`META-INF/sbom/application.cdx.json`.
## Merge Danger
**Door:** two-way
Reverting the version catalog and the BOM import restores 4.1.1 / 2.0.1. No
data or config formats change.
**Blast Radius:** runtime-wide
Every distribution artifact (Jib JVM image, both native images) picks up
pre-GA Boot, Spring AI and MCP SDK (2.2.0-M2) builds. The native images are
exercised by `native.yml`.
