key-decisions:
|
|
- "Mill 1.1.1 for Java 25 compatibility (0.12.x uses ASM that doesn't support class file version 69)"
|
|
- "Use mvnDeps and mvn interpolator (ivy deprecated in Mill 1.x)"
|
|
- "Use _root_.config import to avoid shadowing from zio.config"
|
|
|
|
patterns-established:
|
|
- "Config pattern: Case classes with zio-config-magnolia derivation"
|
|
- "Route pattern: Object with routes val, composed in Routes.scala"
|
|
- "Main pattern: ZIOAppDefault with bootstrap for ConfigProvider"

# Phase 01 Plan 01: Mill Build and ZIO HTTP Server Summary
|
|
|
|
**Mill 1.1.1 build with Scala 3.3.4, ZIO HTTP server on port 8080, HOCON configuration with environment overrides**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 39 min
|
|
- **Started:** 2026-02-04T20:04:29Z
|
|
- **Completed:** 2026-02-04T20:44:00Z
|
|
- **Tasks:** 3
|
|
- **Files created:** 8
|
|
|
|
## Accomplishments
|
|
|
|
- Mill build system configured with all ZIO dependencies for Phase 1
|
|
- Working HTTP server with /health endpoint returning "ok"
|
|
- Configuration infrastructure using zio-config-magnolia for automatic derivation
|
|
- ASCII sun banner displayed on server startup
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create Mill build configuration** - `aedb45f` (feat)
|
|
2. **Task 2: Create project structure and configuration** - `4278b84` (feat)
|
|
3. **Task 3: Create HTTP routes and Main entry point** - `3757cf8` (feat)
|
|
|
|
## Files Created
|
|
|
|
- `build.mill` - Mill build configuration with Scala 3.3.4 and ZIO dependencies
|
|
- `.mill-version` - Pins Mill version to 1.1.1
|
|
- `.gitignore` - Excludes Mill artifacts, IDE files, OS files
|
|
- `summercms/src/Main.scala` - ZIOAppDefault entry point with banner
|
|
- `summercms/src/api/Routes.scala` - Route composition point
|
|
- `summercms/src/api/HealthRoutes.scala` - GET /health endpoint
|
|
- `summercms/src/config/AppConfig.scala` - ServerConfig, DatabaseConfig, AppConfig case classes
|
|
- `summercms/resources/application.conf` - HOCON config with env overrides
|
|
|
|
## Decisions Made
|
|
|
|
1. **Mill 1.1.1 instead of 0.12.x** - System Java 25 (class file version 69) requires newer Mill with updated ASM library
|
|
2. **mvnDeps instead of ivyDeps** - Mill 1.x renamed the dependency method
|
|
3. **_root_.config import** - Avoids shadowing from `zio.*` importing `zio.config`
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 3 - Blocking] Updated Mill version for Java 25 compatibility**
|
|
- **Found during:** Task 1
|
|
- **Issue:** Mill 0.12.11 ASM library doesn't support Java 25 class file version 69
|
|
- **Fix:** Downloaded Mill 1.1.1 launcher, updated .mill-version
|
|
- **Files modified:** .mill-version, downloaded ./mill launcher
|
|
- **Verification:** `./mill resolve _` succeeds
|
|
- **Committed in:** aedb45f
|
|
|
|
**2. [Rule 3 - Blocking] Added .gitignore for Mill artifacts**
|
|
- **Found during:** Task 1
|
|
- **Issue:** Build artifacts (out/, mill executable) would be committed without gitignore
|
|
- **Fix:** Created .gitignore excluding Mill artifacts, IDE files, OS files
|
|
- **Files modified:** .gitignore (new file)
|
|
- **Verification:** `git status --short` no longer shows out/ or mill
|
|
- **Committed in:** aedb45f
|
|
|
|
**3. [Rule 1 - Bug] Fixed import shadowing with zio.config**
|
|
- **Found during:** Task 3
|
|
- **Issue:** `import zio.*` brings `zio.config` into scope, shadowing local `config` package
|
|
- **Fix:** Used `_root_.config.{AppConfig as SummerConfig}` import
|
|
- **Files modified:** summercms/src/Main.scala
|
|
- **Verification:** `./mill summercms.compile` succeeds
|
|
- **Committed in:** 3757cf8
|
|
|
|
---
|
|
|
|
**Total deviations:** 3 auto-fixed (2 blocking, 1 bug)
|
|
**Impact on plan:** All auto-fixes necessary for correctness. No scope creep.
|
|
|
|
## Issues Encountered
|
|
|
|
- SLF4J warning about missing StaticLoggerBinder - benign, zio-http works with NOP logger. Will be resolved when adding proper logging in later phases.
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- Build system ready for database integration (Plan 01-02)
|
|
- All ZIO dependencies already declared for database layer
|
|
- Configuration pattern established for adding more settings
|
|
- Ready to add /ready endpoint once database is connected
