逐步修复 Kotlin/Gradle 构建错误、编译器警告和依赖项问题。调用 kotlin-build-resolver 代理进行最小化、精准的修复。

Kotlin 构建与修复

此命令调用 kotlin-build-resolver 代理，以最小的改动增量修复 Kotlin 构建错误。

此命令的作用

1. 运行诊断：执行 ./gradlew build、detekt、ktlintCheck
2. 解析错误：按文件分组并按严重性排序
3. 增量修复：每次修复一个错误
4. 验证每次修复：每次更改后重新运行构建
5. 报告摘要：显示已修复的内容和剩余问题

何时使用

在以下情况使用 /kotlin-build：

• ./gradlew build 因错误而失败
• Kotlin 编译器报告错误
• ./gradlew detekt 报告违规
• Gradle 依赖项解析失败
• 拉取更改后导致构建失败

运行的诊断命令

# Primary build check
./gradlew build 2>&1

# Static analysis
./gradlew detekt 2>&1 || echo "detekt not configured"
./gradlew ktlintCheck 2>&1 || echo "ktlint not configured"

# Dependency issues
./gradlew dependencies --configuration runtimeClasspath 2>&1 | head -100

# Optional deep refresh when caches or dependency metadata are suspect
./gradlew build --refresh-dependencies

示例会话

User: /kotlin-build

Agent:
# Kotlin Build Resolution

## Initial Diagnostics

```bash
$ ./gradlew build
e: src/main/kotlin/com/example/service/UserService.kt:25:15 Unresolved reference: UserRepository
e: src/main/kotlin/com/example/routes/UserRoutes.kt:42:9 Type mismatch: inferred type is String but Int was expected
e: src/main/kotlin/com/example/routes/UserRoutes.kt:58:5 'when' expression must be exhaustive
```

Errors found: 3

## Fix 1: Unresolved Reference

File: src/main/kotlin/com/example/service/UserService.kt:25
Error: Unresolved reference: UserRepository
Cause: Missing import

```kotlin
// Added import
import com.example.repository.UserRepository
```

```bash
$ ./gradlew build
# 2 errors remaining
```

## Fix 2: Type Mismatch

File: src/main/kotlin/com/example/routes/UserRoutes.kt:42
Error: Type mismatch: inferred type is String but Int was expected

```kotlin
// Changed
val count = call.parameters["count"]
// To
val count = call.parameters["count"]?.toIntOrNull()
    ?: return@get call.respond(HttpStatusCode.BadRequest, "Invalid count")
```

```bash
$ ./gradlew build
# 1 error remaining
```

## Fix 3: Non-Exhaustive When

File: src/main/kotlin/com/example/routes/UserRoutes.kt:58
Error: 'when' expression must be exhaustive

```kotlin
// Added missing branch
when (user.role) {
    Role.ADMIN -> handleAdmin(user)
    Role.USER -> handleUser(user)
    Role.MODERATOR -> handleModerator(user) // Added
}
```

```bash
$ ./gradlew build
# Build successful!
```

## Final Verification

```bash
$ ./gradlew detekt
# No issues

$ ./gradlew test
# All tests passed
```

## Summary

| Metric | Count |
|--------|-------|
| Build errors fixed | 3 |
| Detekt issues fixed | 0 |
| Files modified | 2 |
| Remaining issues | 0 |

Build Status: PASS: SUCCESS

常见的已修复错误

错误	典型修复方法
Unresolved reference: X	添加导入或依赖项
Type mismatch	修复类型转换或赋值
'when' must be exhaustive	添加缺失的密封类分支
Suspend function can only be called from coroutine	添加 suspend 修饰符
Smart cast impossible	使用局部 val 或 let
None of the following candidates is applicable	修复参数类型
Could not resolve dependency	修复版本或添加仓库

修复策略

1. 首先修复构建错误 - 代码必须能够编译
2. 其次修复 Detekt 违规 - 修复代码质量问题
3. 再次修复 ktlint 警告 - 修复格式问题
4. 一次修复一个 - 验证每次更改
5. 最小化改动 - 不进行重构，仅修复问题

停止条件

代理将在以下情况下停止并报告：

• 同一错误尝试修复 3 次后仍然存在
• 修复引入了更多错误
• 需要进行架构性更改
• 缺少外部依赖项

相关命令

• /kotlin-test - 构建成功后运行测试
• /kotlin-review - 审查代码质量
• /verify - 完整的验证循环
