gwt を Hibernate に統合しましたが、hibernate.reveng.xml を作成するときにエラーが発生し、Bean クラスをエンティティ化できませんでした。エラー メッセージ ;

プラグイン「org.eclipse.core.resources」からコードを呼び出すときに問題が発生しました。[ここにリンクの説明を入力][1]

この質問のトピックは 、org.jboss.ide.eclipse.archives.core.WorkspaceChangeListener からの NullPointerException (プラグインからコードを呼び出すときに問題が発生しました: "org.eclipse.core.resources".

私は使っている：

  • JBoss Developer Studio (コア機能) 7.0.1.GA-v20130930-2238-B7 com.jboss.jbds.product.feature.feature.group Red Hat による JBoss
    • (Eclipse->Help->About->Installation Details->Installed Software を参照)
  • JBossTools アーカイブ コア プラグイン 3.4.100.Final-v20130717-0846-B106 (org.jboss.ide.eclipse.archives.core)
    • (Eclipse->ヘルプ->バージョン情報->インストールの詳細->プラグインを参照)

最終的な答えは見つかりませんでしたが、原因を少し絞り込むためのポイントがいくつかあります (不要な場合は、Eclipse でJBOSS Dev Toolsをアンインストールすると解決する可能性があります)。

  • 同様のバグが修正されていましたが、それ以上の説明はありませんでした。

  • 2008: ここに (プラグインコード関連の) 開発者向けヒントがいくつかあります: https://issues.jboss.org/browse/JBIDE-2746?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel&_sscc =t

    • コンポーネントを設定するのを忘れた
