注入插件 gorm import 失败: %w

Error message

注入插件 gorm import 失败: %w

What it means

This error is produced during AST-based code injection into a plugin's initialize GORM file. Before appending a composite literal referencing the plugin's package, the injector calls NewImport(...).Injection(file) to add the required gorm import; if that import injection fails, the original error is wrapped as "注入插件 gorm import 失败". It means the code generator could not modify the plugin's import block, usually because the file's AST structure is unexpected or the import already conflicts.

Solutions

1. Inspect the wrapped cause (%w) in the error message to see the underlying import-injection failure and fix that root problem.
2. Restore plugin/xxx/initialize/gorm.go to the standard generated template (valid package clause, proper import block) and re-run the code generator.
3. Verify the file parses with go/parser (gofmt the file) before injection.
4. If a previous partial injection left a duplicate import, remove it manually and retry.

Example fix

// before (malformed plugin gorm.go)
package initialize
import (
  "gorm.io/gorm"
)

// after (standard template, parses and imports cleanly)
package initialize

import (
  "github.com/flipped-aurora/gin-vue-admin/server/plugin/xxx/model"
  "go.uber.org/zap"
  "gorm.io/gorm"
)

src, err := os.ReadFile(pluginGormFile)
if err != nil { return err }
if _, err := parser.ParseFile(fset, pluginGormFile, src, parser.ParseComments); err != nil {
    return fmt.Errorf("plugin gorm file does not parse: %w", err)
}
if !bytes.Contains(src, []byte("import (")) {
    return errors.New("plugin gorm file lacks an import block")
}

if err := injectGormInit(plugin); err != nil {
    var wrapped error
    if errors.As(err, &wrapped) {
        log.Printf("plugin gorm injection failed: %+v", wrapped)
    }
    return fmt.Errorf("regenerate plugin files and retry: %w", err)
}

When it happens

Trigger: Running the auto-code plugin initialization (injectPluginInitializeGorm / Injection on plugin_initialize_gorm.go) when the target plugin's initialize gorm file cannot be parsed or its import block cannot be updated — e.g. the plugin's gorm.go has a malformed or non-standard import section, or NewImport(a.ImportPath).Injection(file) returns an error.

Common situations: Generating a new plugin whose plugin/xxx/initialize/gorm.go template was hand-edited and lost the standard import block; a file that fails go/parser; duplicate/conflicting import declarations inserted by previous failed runs.
