自动代码任务包含重复目标

Error message

自动代码任务包含重复目标

What it means

errAutoCodeDuplicateTarget is returned by prepareAutoCodeFileTask when the generated task contains two entries that resolve to the same target file path (or equivalent duplicates). Committing such a task would write the same file twice with possibly different content, so preparation fails fast.

Solutions

1. Review the request's package/abbreviation/template settings so each generated file maps to a unique path.
2. Deduplicate the target list before preparing the task.
3. Fix custom templates that emit the same output path more than once.
4. Split the request into separate tasks if distinct content must land in the same file.

Example fix

// before: two templates write server/api/v1/foo.go
outputs: ["server/api/v1/foo.go", "server/api/v1/foo.go"]
// after
outputs: ["server/api/v1/foo.go"]

seen := map[string]bool{}
for _, p := range targetPaths {
    if seen[p] {
        return fmt.Errorf("重复目标路径: %s", p)
    }
    seen[p] = true
}
// safe to prepare the task

task, err := prepareAutoCodeFileTask(layout, req)
if err != nil {
    if errors.Is(err, errAutoCodeDuplicateTarget) {
        return fmt.Errorf("请检查模板输出/请求参数, 去除重复目标文件: %w", err)
    }
    return err
}

When it happens

Trigger: A create/preview request whose template outputs map onto the same destination — e.g. duplicated template entries, a package/abbreviation combination colliding paths, or a request listing the same file twice (see TestPrepareAutoCodeFileTaskRejectsEquivalentDuplicateTargets).

Common situations: Custom templates duplicating output paths; autocode payloads with overlapping struct/package settings; merged requests where frontend and backend file sets intersect.
